cross compile error about aws-lc HOT 7 CLOSED

Hi, thanks for your report.

Looking at the error output I can see that CMake attempts to compile and link a small test program testCCompiler.c. This is a sanity check of your compilers ability to function, soemthing CMake does, and doesn't use any AWS-LC code. Extracting the specific build commands from the error log we can see it is independent of AWS-LC:

/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc   -O2 -pipe -g -feliminate-unused-debug-types  -fPIE   -o CMakeFiles/cmTC_a657f.dir/testCCompiler.c.o   -c /home/wildwindy/NFS/AWSSDK/sdkv2/build/crt/aws-crt-cpp/aws-lc/CMakeFiles/CMakeTmp/testCCompiler.c

/opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc -O2 -pipe -g -feliminate-unused-debug-types   -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed  -rdynamic CMakeFiles/cmTC_a657f.dir/testCCompiler.c.o  -o cmTC_a657f 

testCCompiler.c is very simple, something like:
https://github.com/Kitware/CMake/blob/master/Modules/CMakeTestCCompiler.cmake#L38

Did this work before the SDK included AWS-LC in its dependencies?

Adding to my previous comment. I do see that the first compiler check succeeded:

-- The C compiler identification is GNU 4.9.1
-- The CXX compiler identification is GNU 4.9.1
-- Check for working C compiler: /opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
-- Check for working C compiler: /opt/poky/1.7/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc -- works

Not sure how to explain that.

I assume you are using Poky and have build a cross-compilation environment. I'm not very familiar with Poky. Would you be able to share some information about how your build your cross-compilation environment? Without that I think it would be hard for me to produce it locally.

Hi, are you still experiencing the reported issue?

I would be happy to try and help resolve it.

Sorry for my delay. I think your first comment showed me that POKY can not build AWS-LC.
Farther more , In our second comment ，did you testing in crosscomplilation environment?
At last ,I uploaded my crosscomplilation environment to "https://thinkgrowledweb.s3.us-west-2.amazonaws.com/x86_64-pokysdk.tar.gz"
Hope it give you more information

Would you be able to provide more steps to reproduce this build issue using the cross-compilation environment that you provided?

Hi, just checking again if you'd be able to provide more steps to reproduce this build issue using the cross-compilation environment that you provided?
