Bug 269734 – sys-apps/grep: Fix pcre cross-compilation

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bertrand Jacquin 2009-05-13 18:59:40 UTC]

Here is fix to replace configure.in attempt to exec host pcre-config by
a pkg-config method. "Previous" method was not really adapted if you try
to cross-compile grep. If host have pcre-config, it contain host cflags
and ldflags which make linker not happy :

i586-geode-linux-uclibc-gcc  -Os -pipe -march=k6-2 -fomit-frame-pointer
-I/usr/i586-geode-linux-uclibc/usr/include/
-I/usr/i586-geode-linux-uclibc/include/    -o grep  grep.o dfa.o kwset.o
search.o grepmat.o ../lib/libgreputils.a -L/usr/lib64 -Wl,-Bstatic
-lpcre -Wl,-Bdynamic
/usr/libexec/gcc/i586-geode-linux-uclibc/ld: skipping incompatible
/usr/lib64/libpcre.a when searching for -lpcre
/usr/libexec/gcc/i586-geode-linux-uclibc/ld: cannot find -lpcre
collect2: ld returned 1 exit status
make[2]: *** [grep] Error 1

The attached patch are for grep 2.5.1a and 2.5.4.

Reproducible: Always

Steps to Reproduce:
1. crossdev -t i586-geode-linux-uclibc
2. emerge-wrapper --init
3. USE=pcre i586-geode-linux-uclibc -vat grep

grep-2.6 uses pkg-config now to find pcre
