Description Michael Jennings (KainX) 2004-12-29 20:37:08 EST
Description of problem:
Use of the AC_CHECK_TYPE() autoconf macro fails when the compiler
flags contain -Werror due to missing prototypes for longval() and

Version-Release number of selected component (if applicable):


How reproducible:

Every time.

Steps to Reproduce:
1.  Use AC_CHECK_TYPE(char, 1) in configure.in, or download
libast-0.6.1.tar.gz from http://www.eterm.org/download/ and use that.
2.  export CFLAGS='-O0 -g3 -march=pentiumpro -W -Wall
-Wmissing-prototypes -Wmissing-declarations -Wall -Werror -std=c99
3.  ./autogen.sh && make distcheck  
Actual results:

checking size of char... configure: error: cannot compute sizeof
(char), 77
See `config.log' for more details.
make: *** [distcheck] Error 1

Expected results:

configure script should complete without errors though "make
distcheck" will fail later on for other reasons.

Comment 1 Daniel Reed 2005-01-21 14:43:48 EST
This is now fixed in upstream Autoconf CVS, and will be available in the next
upstream release.
Comment 4 Karsten Hopp 2006-05-08 08:07:48 EDT
added patch to CVS so that this doesn't get lost.
this will be fixed when we need to issue the next erratum
