Re: Compiling problem on AIX

[Tilo Eckert <tilo.eckert@xxxxxxx>]

Hi Robin,

we compile libssh for z/OS / USS and AIX. On AIX, we use gcc. So I
cannot help you regarding xlc on AIX specifically. However, we use a
custom makefile and c99 (xlc) to compile libssh on z/OS and USS.

Here is an example call for compiling on USS:
> c99 -q32 -Wc,goff -Wc,dll -qexportall -qarch=8 -qtune=10 -qtarget=zOSV1R13 -D_XOPEN_SOURCE=600 -DLIBSSH_EXPORTS -D_LARGEFILE64_SOURCE -DNI_MAXHOST=1025 -O3 -DNDEBUG -D__EBCDIC__ -Ilibssh/include -Ibin/ussz31/openssl/include -o build/ussz31/libssh/messages.o -c libssh/src/messages.c

I think, the xlc executable expects C89 source code by default, which
explains your issue with double slash comments. libssh requires C99.

Regards,
Tilo
