Hi list,
this is my first post here, so I hope this is the right list and I am
not violating the netiquette.
I'm a complete autoconf newbie. For a small project I want to test,
whether the cuda NVCC compiler's version is appropriate. The version is
appropriate, when the output of the command "nvcc --version" contains
the string "release 3.0". If not, I want to print a warning.
AS_IF([test m4_index([m4_esyscmd([nvcc --version])], [release 3.0]) -eq
-1],[
AC_MSG_WARN([NVCC compiler version is NOT 3.0!])
])
Unfortunately the condition in the AS_IF always evaluates to true, so
the warning is always printed. M4 seems to treat the esyscmd as a
string. I have tried every thinkable way of quoting this. Any ideas?
Thanks,
Matthias
