Hi,
thanks for your awesome work it really helps us a lot. We have integrated it into ARToolKit and it saved us quite some time 👍 .

Recently I came across a weird error on Android arm64-v8a architecture devices. I hope that you can find the time and try to reproduce it and if possible fix it.
You can find my changes to your Android example app on my fork in this branch:
https://github.com/ThorstenBux/curl-android-ios/tree/curl_arm64-v8a

Basically, I added form data and forced the build to only produce an arm64-v8a library. I already tried several different things to solve it but none helped. Please let me know if you can help me out with this. I'm more than happy to help where ever I can to reproduce that error for you.

Thank you very much in advance

Hi,
I am trying to use C++ in my Android app. I want to write all the business logic in C++ and then use it from Android, iOS and Windows apps. That's the dream goal and your pre-compiled libraries are going to help me a lot.
I have one question. Is there a dependency on libiconv or is it included?

Thanks,
Vinod

Thanks

how to build libcurl without https(ssl)

I was initially getting an error openssl/opensslconf.h was not found. So I created a symlink from /user/local/opt/openssl/include/openssl to /usr/local/incude

But now, getting many other errors. What went wrong?

The only file resembling the opensslconf.h is include/openssl/opensslconf.h.in, but that seems to be a template of some sorts.

Any idea what went wrong?

hello,

I thank you so much for the effort you have put in this project, it is well done.

I just wonder how did you generate the header file, or did you type it yourself?

Thanks!

Hi,

I'm trying to build libcurl for android armv7-a with a recent NDK (r17b) for a targeted platform android-23, but I can't (cross compile from debian 64bit).

My error message is "c compiler cannot create executables"... Any advertisements on this topic ?

Thank you in advance

Hello, After upgrade to latest NDK 11 I see following linking error, probably libcurl rebuild is required to fix that issue

HI, libcurl uses in iOS multithread programming, have a crash error, the reason may be NDS lookup timeout, how to solve it?

pls help, thanks.

I am using your build scripts and sources to build static .a libCurl libraries and I want to use them in an android project that has C++ implementations that call on libCurl APIs. I'm getting a bunch of undefined reference to curl calls such as the following:

Thanks for the project. I have managed to run the script successfully, however, the output file size (libcurl.a) is almost 5mb, is there anyway to make it alot smaller. I just needed http/https protocol access. I have also tried disabling other protocols in ./configure section but still doesn't help. Any help will be greatly appreciated. Thanks

I found prebuilt libraries for Android only support ArmV7,V8 and x86*. Could you help build a Arm version?

How to build prebuilt version without ssl?

Hi, I am trying to run your build_Android.sh but in the line 25 the script can't find the "./Configure" command. How do I install it?I get my way around the SDK well, but I am a n00b with the NDK.
Trying to compile with Ubuntu.

When trying to build according to build instructions, I get the following error

....
jni/../../openssl/bio_ssl.c:63:10: fatal error: 'opensll/crypto.h' file not found

crypto.h is in the opensll/crypto folder. In general it seems that header file locations are wrong all over the openssl sourcefiles. So what is the right way to solve this?

when i add LOCAL_LDLIBS += -lz in Android.mk

then

Android NDK: WARNING:jni/Android.mk:curl: LOCAL_LDLIBS is always ignored for static libraries

Not sure if this is a curl issue or an issue with the build, but CURLOPT_PINNEDPUBLICKEY doesn't work on iOS pre-built binaries, but works fine on Android (with OpenSSL).

I'm trying to enable pinning in our apps that use this library for both iOS and Android and the Android one works fine - correct public key it works as before we added the setting, wrong public key and it gives me an error saying I cannot connect.

Code is as follows:

      CURLcode c = curl_easy_setopt(curl, CURLOPT_FAILONERROR, 1);
        fprintf(stderr, "Set Fail on Error: %s\n",
                curl_easy_strerror(c));
        c = curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 1);
        fprintf(stderr, "Set verify peer: %s\n",
                curl_easy_strerror(c));
        c = curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 2);
        fprintf(stderr, "Set verify host: %s\n",
                curl_easy_strerror(c));
        c = curl_easy_setopt(curl, CURLOPT_PINNEDPUBLICKEY,
                             "sha256//nhEOGkhMcl5uqf13KxUPoCgXYXCKA8A4E+j9JiL+UB8=");
        fprintf(stderr, "Set pinned key: %s\n",
                curl_easy_strerror(c));

The output from this on iOS is:

ENABLING PINNING
Set Fail on Error: No error
Set verify peer: No error
Set verify host: No error
Set pinned key: Error

When I look at the curl return code where I'm setting the pinned key, it's CURLE_NOT_BUILT_IN.

Digging into the curl source, I can see this section in lib/setopt.c:

  case CURLOPT_PINNEDPUBLICKEY:
    /*
     * Set pinned public key for SSL connection.
     * Specify file name of the public key in DER format.
     */
#ifdef USE_SSL
    if(Curl_ssl->supports & SSLSUPP_PINNEDPUBKEY)
      result = Curl_setstropt(&data->set.str[STRING_SSL_PINNEDPUBLICKEY_ORIG],
                              va_arg(param, char *));
    else
#endif
      result = CURLE_NOT_BUILT_IN;
    break;

As far as I can tell, the enabling of the DarwinSSL backend in the prebuilt binaries build script should define USE_SSL (curl_setup.h) which leads me to the Curl_ssl->supports bit for SSLSUPP_PINNEDPUBKEY is not set. The docs for this feature (https://curl.haxx.se/libcurl/c/CURLOPT_PINNEDPUBLICKEY.html) say that support should be from 7.54.1: SecureTransport/DarwinSSL on macOS 10.7+/iOS 10+ and I'm using the 7.60 release.

I've confirmed this by pulling the curl version info that reports as follows:

My attempts to manually build here to try things have been scuppered by this error:

url.c:55:2: error: "We can't compile without socket() support!"

..but I've seen the other tickets (e.g. #19 ) where you point people to run xcode-select --install, which just says:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

I assume this difficulty in checking anything is an Xcode / Mojave issue but I see from #56 you can't upgrade until the new year.

In the meantime, any ideas where the issue for this lies?

Hi and thanks for your efforts on this one. It has been working really well with the Curl 7.48 version.

Today however I wanted to update to 7.50.3 and ran into some issues. It seems some c files has to be removed from the .mk but even after that I got duplicate definition problems.

If you have the time to see if we the script can support the latest version of curl it would be great.

Hi,

OpenSSL build just fine but curl's configure process is broken with NDK r16 unified headers:

Android/sdk/ndk-bundle/prebuilt/darwin-x86_64/bin/../../../toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/bin/arm-linux-androideabi-cpp" fails sanity check

Thank you for the awesome project and keep up the good work.

I was happy to see the prebuilt curl libraries, and I had assumed it would built. Unfortunately my trial turned out otherwise:

1. Pull down the source code
2. Enter the folder:test-android-project\app\src\main
3. Run ndk-build.cmd from a windows command console

I got a bunch of errors similar to the following:

Hello,

I am building a cross platform SDK in C (common for Android/iOS/Windows) in which I want to use curl. Can I use your library?

Hi,

For the prebuilt android libcurl with openSSL, is there a definition for what are the options enabled ? FTP ,file ,etc

how to merge follow libcurl.a file to only one libcurl.a file?
armeabi/libcurl.a
armeabi-v7a/libcurl.a
...

Hi Gustavo,

Thank for your repositories.
I Compiled very well thinking to find cURL binaries for android M but I can not find them
Do you have any advice about?
Regards,

First, thanks for providing this repo and keeping it up to date (I noticed your Jul 2nd update). You rock. cURL is painful to build for Android from the official repos.

curl_setopt()'s CURLOPT_CAPATH specifies the path to a certificate file. Unfortunately, libcURL doesn't read inside APK files. To the best of my knowledge, CURLOPT_SSL_VERIFYPEER can't work on Android, and if you try to connect to an https endpoint, it'll just fail with errorcode CURLE_SSL_CACERT.

Is there a way to specify a cert file on Android? Have I missed something?

Thanks!

When I link this prebuilt library, I get this error msg:
undefined reference to 'ENGINE_load_gost'
undefined reference to 'ENGINE_load_padlock'
undefined reference to 'ENGINE_load_ubsec'
undefined reference to 'ENGINE_load_sureware'
...

I am new to this, I googled it but got nothing useful. please help me.

Hi !

Thank you so much for your work !
I was wondering if you could update your android sample please.
Because I'm struggling setting up the lib with Cmake

Thank you !

Urgent: I want to build libcurl with --with-ca-bundle option in build_Android.sh. Every time i pass a new cacert.pem downloaded from https://curl.haxx.se/docs/caextract.html from this site and build library, after putting that in android, curl response code is always 77 (CURLE_SSL_CACERT_BADFILE). What i am doing wrong. i am building curl with this :
./configure --host=arm-linux-androideabi --target=arm-linux-androideabi
--with-ssl=$SSLPATH
--enable-static
--disable-shared
--disable-verbose
--enable-threaded-resolver
--enable-libgcc
--enable-ipv6
--with-ca-bundle=cacert.pem
It builds fine. But can not establish ssl connection with https site.

Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.

If the paths for an install of MacPorts are present...
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
...the build will fail due to using the wrong libraries.

This is easily remedied by removing the Macports path and continuing.

Cannot compile on iOS using build_iOS.sh because:

  CC       libcurl_la-ldap.lo
url.c:55:2: error: "We can't compile without socket() support!"
#error "We can't compile without socket() support!"

I don't really need ldap any how -- just barebones HTTP/HTTPS support.

I'm trying to link against the pre-built static libraries for both iOS and Android.

The iOS side is working well (thanks 👍 ) but the Android side is failing no matter what I do.

(Note - the Android sample app in the repo also fails the build with the same errors)

Is there an additional library I need to be linking against?

I'm using Android Studio 2.2.1 and have tried building against NDKs r10e and r13...

When linking the library against iOS, i get the following errors at build time.

Hello, first of all:

Thank you very much for this repository, you are a gift for everybody who have to use libcurl in an android app.

Google announced to replace OpenSSL with its own fork BoringSSL in the future on Android. As this is already available via googlesource would it be possible that you can provide libcurl static builds with boringSSL support?

Afaik curl itself support compiled with BoringSSL since 7.44.0

Thank you!

Hi

This curl building script seems to do its job well and I'd like to use it in one of my projects. What is the license of this repository? Can I fork and use it for an open source project? Or can I just download the code without forking and integrate it into my solution? What about commercial use?

Thank you

Regards, Darioxz

My latest update to Google Play is returning the following error:

Your app utilizes a version of OpenSSL that contains one or more security vulnerabilities. Please migrate your app to OpenSSL 1.02f/1.01r or higher...  If you’re using a 3rd party library that bundles OpenSSL, you’ll need to upgrade it to a version that bundles OpenSSL 1.02f/1.01r or higher.

To confirm your OpenSSL version, you can do a grep search for:

$ unzip -p YourApp.apk | strings | grep "OpenSSL"

I ran the following command to confirm your commit message "Updated to cURL 7.48 and OpenSSL 1.0.1s" and what Google stated in their email:

unzip -p ReelContent.16.07.23.3.apk | strings | grep "OpenSSL"

and I saw the following output:

UI_OpenSSL
OpenSSLDie
...
OpenSSL RSA method
OpenSSL default user interface
OpenSSL 'dlfcn' shared library method
You need to read the OpenSSL FAQ, http://www.openssl.org/support/faq.html
OpenSSL default
SSLv2 part of OpenSSL 1.0.1o 12 Jun 2015
...and much more

I have done some research into how to update your openssl submodule locally with The OpenSSl 1_0_2 branch, but I may need some assistance doing that.

Can you help with this, or should I consider options other than what I have already tried?
