idlpp-cxx's Introduction

CXX Idl compiler for CycloneDDS

This project provides an idl compiler to compile datatypes that can be used in the CXX API for CycloneDDS

This compiler will be replaced with our new idl compiler which is currently under development here

Requirements for the CXX Idl compiler

In order to build the Idl compiler you need a Linux, Mac or Windows 10 machine with the following installed on your host:

Git
CMake, version 3.7 or later. (Version 3.6 should work but you will have to edit the cmake_minimum_required version.)
Java JDK, version 8 or later, e.g., OpenJDK 11.
Apache Maven, version 3.5 or later.

Building

Building the Idl compiler, requires only a few simple steps. There are some small differences between Linux and macOS on the one hand, and Windows on the other. For Linux or macOS:

$ git clone https://github.com/ADLINK-IST/idlpp-cxx.git
$ cd idlpp-cxx
$ mkdir build
$ cd build
$ cmake <cmake-config_options> ..
$ cmake --build .

and for Windows:

$ git clone https://github.com/ADLINK-IST/idlpp-cxx.git
$ cd idlpp-cxx
$ mkdir build
$ cd build
$ cmake -G "<generator-name>" <cmake-config_options> ..
$ cmake --build .

where you replace <generator-name> by one of the ways CMake generators offer for generating build files. For example, "Visual Studio 15 2017 Win64" would target a 64-bit build using Visual Studio 2017.

The <cmake-config_options> can be ignored or replaced. A few of the most common options are: -DCMAKE_INSTALL_PREFIX=<install-location> -DCMAKE_BUILD_TYPE=Debug

$ cmake -DCMAKE_BUILD_TYPE=Debug ..

Packaging

If you want to package the product, the config step and build step are slightly different compared to how it is normally build.

The -DCMAKE_INSTALL_PREFIX=<install-location> option should be added to the configuration, where the <install-location> is replaced by the directory under which you would like to install the Idl compiler.

During the build step, you have to specify that you want to build the install target as well.

This would make the build look like

$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=<install-location>  ..
$ cmake --build . --target install

Don't forget the generator when building on Windows.

After the build, required files are copied to:

<install-location>/lib
<install-location>/share

The <install-location> directory is will be used to create the package(s).

$ cpack

Depending on the target, you now have packages.

idlpp-cxx's Issues

[Bug] Linker Error on Clang 13 Compiler

Hi,
while compiling idlpp-cxx with the latest clang stable release i encountered the following linker errors:

/usr/bin/ld: CMakeFiles/cppgen.dir/__/ppresources/ospli/src/cpp/code/set.c.o:(.bss+0xc): multiple definition of `expr_sharp'; CMakeFiles/cppgen.dir/__/ppresources/ospli/src/cpp/code/eval.c.o:(.bss+0xc): first defined here

Happens on idlpp-cxx-1.0.0 and master branch. With clang-10 everything compiles. I guess this happens due some global declarations in header files.

Affected global declarations in the following files:
idlpp/ppresources/ospli/src/cpp/code/expr.h - int expr_sharp;
idlpp/ppresources/ospli/src/cpp/code/if.h - IF *ifstack;
idlpp/ppresources/ospli/src/cpp/code/if.h - int n_skipped_ifs;
idlpp/ppresources/ospli/src/tools/idlpp/code/idl_genIdlHelper.h - os_iter idl_idlScopeKeyList;
idlpp/ppresources/ospli/src/tools/idlpp/code/idl_genIdlHelper.h - os_iter idl_idlScopeStreamsList;

I guess these variables need to be declared, but i'm not sure about the implications in the overall system.

Vector of string is not handled correctly

Hello everyone,
I am having troubles working with a vector of strings. I have the following IDL file:

module Msg
{
struct StringSeq {
	long id;
	sequence<string<10>, 5> names;
};
#pragma keylist StringSeq id
};

which should allow me to work with a vector with at most 5 strings of maximal 10 characters.
Now, I would like to write a message using cyclonedds-cxx. To this end, I just took the helloworld example, I changed the IDL file with mine above and replaced the content of the file publisher.cpp with:

#include <iostream>
#include "dds/dds.hpp"
#include "StringSeq_DCPS.hpp"
using namespace org::eclipse::cyclonedds;
int main() {
    dds::domain::DomainParticipant participant(domain::default_id());
    dds::topic::Topic<Msg::StringSeq> topic(participant, "StringSeq");
    dds::pub::Publisher publisher(participant);
    dds::pub::DataWriter<Msg::StringSeq> writer(publisher, topic);
    std::vector<std::string> stringVector{"Name1", "Name2", "Name3"};
    Msg::StringSeq msg(18, stringVector);
    writer.write(msg);
    std::cout << "Messagge written." << std::endl;
    return EXIT_SUCCESS;
}

However, the execution results in an error when the function __Msg_StringSeq__copyIn in the file StringSeqSplDcps.cpp tries to "strncpy" the first entry of stringVector in an invalid location, since the components of dest0 have not been initialized properly in the previous line of code:

dest0 = (length0 == 0) ? 0 : (char * *)dds_alloc(length0 * sizeof(char *));

Is this problem caused because a corresponding for-loop is missing in the function idl_seqAllocBuffer in the file idl_genLiteISOCxxCopyin.c?

Thank you in advance, any help would be appreciated.
Best regards,
Ettore Vidotto
