System: FreeBSD libertas.emma.line.org 4.11-RC3 FreeBSD 4.11-RC3 #17: Mon Jan 17 21:44:19 CET 2005 root@libertas.emma.line.org:/usr/src/sys/compile/LIBERTAS i386
>Description:
GCC 2.95.4 cannot compile e2fsprogs development version while GCC 3.3 is fine.
The preprocessor fails to expand a macro with a longish name, error message:
making all in lib/e2p
gmake[2]: Entering directory `/tmp/e2fsprogs/build/lib/e2p'
CC ../../../lib/e2p/feature.c
../../../lib/e2p/feature.c:50: `EXT3_FEATURE_INCOMPAT_EXTENTS' undeclared here (not in a function)
../../../lib/e2p/feature.c:50: initializer element is not constant
../../../lib/e2p/feature.c:50: (near initialization for `feature_list[12].mask')
gmake[2]: *** [feature.o] Error 1
type: less lib/e2p/feature.i and type /EXT3 and press the enter key
to see the problem area:
{ 1 , 0x0008 ,
"journal_dev" },
{ 1 , EXT3_FEATURE_INCOMPAT_EXTENTS,
"extents" },
{ 1 , 0x0010 ,
"meta_bg" },
GCC 3.3 will properly replace EXT3_FEATURE_INCOMPAT_EXTENTS with 0x0040
(install lang/gcc33, then gmake CC=gcc33)
>How-To-Repeat:
- install devel/gmake port
- install devel/bibktkeeper port (see PR #76208 if it's uncommitted)
- cd to a writable directory with some 30 MB room
- type these commands to check out, configure and build the code:
#
# the next three commands will clone the repository and check it out
#
bk clone -qr'tytso@think.thunk.org|ChangeSet|20050117193220|14963' \
bk://thunk.org:5000/ e2fsprogs/
cd e2fsprogs
bk -Ur get -Sq
#
# now do the build
#
mkdir build
cd build
../configure -C CFLAGS="-O -save-temps"
gmake
