Details:
In environments which pass in -g to CFLAGS, compilation can fail or error due
to the following line in configure.in
CFLAGS=`echo $CFLAGS | sed 's/ -g //g'`
For example:
cc -DHAVE_CONFIG_H -I. -I../.. -DLOCALEDIR=\"/usr/local/share/locale\"
-I/usr/local/include -D_THREAD_SAFE -Wall -W
-Werror-implicit-function-declaration -pipe -pipe-I/usr/local/include
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -g -O0
-I/usr/local/include -D_THREAD_SAFE -DWEECHAT_VERSION=\"0.3.0\" -MT
wee-infolist.o -MD -MP -MF .deps/wee-infolist.Tpo -c -o wee-infolist.o
wee-infolist.c
cc: unrecognized option '-pipe-I/usr/local/include'
and
cc -DHAVE_CONFIG_H -I. -I../.. -DLOCALEDIR=\"/usr/local/share/locale\"
-I/usr/local/include -I/usr/local/include -D_THREAD_SAFE -Wall -W
-Werror-implicit-function-declaration -pipe -pipe
-march=nocona-I/usr/local/include -DHAVE_GNUTLS -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -g -O0 -pthread
-I/usr/local/include -D_THREAD_SAFE -DWEECHAT_VERSION=\"0.3.0\" -MT weechat.o
-MD -MP -MF .deps/weechat.Tpo -c -o weechat.o weechat.c
weechat.c:1: error: bad value (nocona-I/usr/local/include) for -march=
switch
weechat.c:1: error: bad value (nocona-I/usr/local/include) for -mtune=
switch
*** Error code 1
The problem is that it removes a space before and after any occurance of "-g"
along with the "-g" itself. This will cause any CFLAGS arguments immediately
prior and following the " -g " to get concatenated. In the examples above,
this produces "-pipe-I/usr/local/include" and
"-march=nocona-I/usr/local/include".
The attached patch will replace " -g " with " ", thereby not concatenating
the prior and following CFLAGS arguments.
