[CMake] cmake 2.8.12.2 fails on AIX 6.1 with ld: target noipath not found
Hello I installed cmake 2.8.12.2 on AIX 6.1 with the intention of building MySQL. The build fails so I tried to cmake the simplest test program, and I get the same failure. The error is ld: target noipath not found It seems to me that noipath is a directive to the linker, so the linker should not be looking for a target called noipath. Can anyone help with this? Thanks Graham Russell Details: I installed the cmake-2.8.12.2-AIX-powerpc.tar.gz file. The AIX version is AIX 6100-03-03-0943. I created a folder CMake/Tests/Tutorial containing the first step in http://www.cmake.org/cmake/help/cmake_tutorial.html: CMakeLists.txt tutorial.cxx Then ran cmake as below: pvm-vangogh-94:grussell [602] bin/cmake . -- The C compiler identification is GNU 4.4.4 -- The CXX compiler identification is GNU 4.4.4 -- Check for working C compiler: /usr/local/bin/gcc -- Check for working C compiler: /usr/local/bin/gcc -- broken CMake Error at /mnt/research/grussell/cmake-2.8.12.2-AIX-powerpc/share/cmake-2.8/Modules/CMakeTestCCompiler.cm ake:61 (message): The C compiler /usr/local/bin/gcc is not able to compile a simple test program.

[CMake] cmake 2.8.12.2 fails on AIX 6.1 with ld: target noipath not found
Thanks for the response, Bill.
I confirmed that the compiler install works fine:
pvm-vangogh-94:grussell [625] /usr/local/bin/gcc hello.c -o hello
pvm-vangogh-94:grussell [626] ./hello Hello World!
I also tested it with your simple program and it also compiles OK and runs.
I think the problem lies in the options that CMake uses to test the AIX compile
environment.
Thanks
Graham Russell

This is not a CMake problem. Your compiler install is bad.
CMake is testing the compile of a very simple .c file and it is not work.
I suspect that a simple program like this:
int main() { return 0;}
will not compile and link with the /usr/local/bin/gcc on your system.
Create the above file and try to compile it without cmake and just gcc.
It should get the same error. I would suggest that you reinstall gcc on the
machine.

Re: [CMake] cmake 2.8.12.2 fails on AIX 6.1 with ld: target noipath not found
Seems like there are 2 choices for a solution:
1. Change CMake so it uses the IBM linker instead of the GNU linker. What
settings would I need to change in the cmake files to try this?
2. Change the linker options so they will work for the GNU linker.
I tried option #2 by removing -bnoipath from the Modules/AIX-GNU.cmake file.
This enabled cmake to run successfully on test files and on the MySQL package.
However, my ultimate aim being to build MySQL, the make did run into errors
subsequently, so I would like to try option #1 also. I am interested if you
have an opinion as to whether option #1 or option #2 would give me a better
shot at building MySQL.
Further to your question Would you be willing to run a nightly
dashboard with this configuration so we can test it over time?
I would be willing, but need to know how to do this and what it involves.
Thanks
Graham Russell

OK, from the log you sent, we can see that CMake is passing some stuff to the
linker:
/usr/local/bin/gcc
CMakeFiles/cmTryCompileExec680887608.dir/testCCompiler.c.o -o
cmTryCompileExec680887608 -Wl,-brtl,-bnoipath,-bexpall
-Wl,-blibpath:/usr/lib:/lib
I think the problem is that you are using the GNU linker, and CMake seems to be
expecting the AIX linker to be used even with gcc.
You can see this is the linker used:
/usr/local/lib/gcc/powerpc-ibm-aix6.1.0.0/4.4.4/../../../../powerpc-ibm-aix6.1.0.0/bin/ld:
Which is the GNU linker and not the AIX linker which supports and needs that
flag.
You should be able to change this in Modules/AIX-GNU.cmake
which has this:
set(CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS
-Wl,-brtl,-bnoipath,-bexpall) # +s, flag for exe link to use shared lib
That should get you going. I will think about a solution that can be
incorporated into CMake. Would you be willing to run a nightly
dashboard with this configuration so we can test it over time?
Thanks.
