Make issue: using -traditional without -E #4

Closed Jiehong closed 8 years ago

Jiehong commented 8 years ago

Hello,

Here, when trying to compile dtach, gcc conplains that -traditional no longer works without -E.

GCC version used is 4.3.2.

Here is the complete error message:

gcc -traditional -L/opt/Python-2.7/lib -L/opt/Python-2.7/lib  -W -Wall -I.   -c -o attach.o attach.c
gcc: GNU C no longer supports -traditional without -E
make: *** [attach.o] Error 1

Adding the option in Makefile solve this issue though.

But, then it won't compile with the following error:

gcc -traditional -E -L/opt/Python-2.7/lib -L/opt/Python-2.7/lib  -W -Wall -I.   -c -o attach.o attach.c

I'm unsure why this is failing though.

I forgot to add the version of dtach I'm trying to build: v0.9 (tag).

I'd like to attach the output of ./configure, as it may be useful.

Those -L/opt/Python-2.7/lib items are not normally there. But the odd ones are the use of ggrep most modern OSs have a good enough /usr/bin/grep. And the result of the 'Traditional' test; it should only fail on ancient Unix variants.

There will be a config.log file in the directory with lots of details; you'll need to upload that somewhere.

Jiehong commented 8 years ago

It's on a Suse Linux Enterprise Server 11 SP1, with Linux 2.6.32.23.

So, yeah, it isn't that new, but can't change that though.

ggrep is calling grep behind (version 2.5.2).

Here is my config.log file (cleaned a bit): https://framadrop.org/r/RzK-UvhQ6D#fgzfV8IKGN051vo7ejPtp5FdErco0CO8DNGiJJRSF4k=

Thank you for your kind help :)

rdebath commented 8 years ago

Oooo, is that ggrep a shell script? Is it preserving the exit status of grep correctly? Can you try ...

ac_cv_path_GREP=/bin/grep  ./configure
Jiehong commented 8 years ago

You are right. It does work with forcing the value of ac_cv_path_GREP.

Checking the shell script of ggrep confirms your hypothesis: the return status is not preserved.

I'm closing this ticket then.

Thanks a lot!
