Hi Kim,
The problem is, the output file is slightly different
than the one produced on linux and it won't run as an executable. I
noticed, for example, that in the version linked on windows there is the
undefined symbol "printf" which appears to have become "puts" instead in
the linux version.
I suspect that the printf/puts variance may be a red herring.
Anyway I'm wondering if anyone knows what is happening here.
k@system:/shared$ ./Test
bash: ./Test: No such file or dire
What happens if you run "file ./Test" ?
What happens if you run "ldd ./Test" ?
Also it appears that you are linking against different math's libraries:
Linking on Windows:
attempt to open I:\Linux\libs\lib\x86_64-linux-gnu\libm-2.17.so succeeded
Linking on linux:
attempt to open /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/libm.so succeeded
And that as a result you are pulling in the wrong C library:
> Linking on Windows:
ld-linux-x86-64.so.2 needed by I:/Linux/libs/lib/x86_64-linux-gnu/libc-2.17.so
Also - which version of the linker are you using ? If it is an old
version then that may be causing you problems.
Cheers
Nick
