我正在使用Fedora x86_64。它使用/lib64
,/usr/lib64
和朋友。我有以下*.pc.in
文件:
$ cat libcryptopp.pc.in
prefix=@prefix@
exec_prefix=@exec_prefix@
libdir=@libdir@
includedir=@includedir@
...
我的config.site
有以下内容。它是从Fedora的config.site
/usr/share/config.site
复制的。由于config.site for vendor libs on Fedora x86_64而使用了该副本。
$ cat /usr/local/share/config.site
...
# Note: This file includes also RHEL/Fedora fix for installing libraries into
# "/lib/lib64" on 64bit systems.
if test -n "$host"; then
# skip when cross-compiling
return 0
fi
if test "$prefix" = /usr \
|| { test "$prefix" = NONE && test "$ac_default_prefix" = /usr ; }
then
test "$sysconfdir" = '${prefix}/etc' && sysconfdir=/etc
test "$sharedstatedir" = '${prefix}/com' && sharedstatedir=/var
test "$localstatedir" = '${prefix}/var' && localstatedir=/var
ARCH=`uname -m`
for i in x86_64 ppc64 s390x aarch64; do
if test $ARCH = $i; then
test libdir='${exec_prefix}/lib64'
break
fi
done
fi
然而,在Autoconf处理我的*.pc.in
文件后:
$ autoreconf --install --force
...
$ ./configure
...
$ cat libcryptopp.pc
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
...
请注意libdir=${exec_prefix}/lib
,而不是libdir=${exec_prefix}/lib64
。
GCC肯定会为该软件包构建64位二进制文件。我没有添加-mx32
或-m32
:
$ gcc -dumpmachine
x86_64-redhat-linux
为什么使用了错误的lib/
目录,我该如何解决?
答案 0 :(得分:0)
/usr/local/share/config.site
错了。虽然它是从Fedora的config.site
复制并放在/usr/local/share
中,但前缀目录是错误的。前缀测试应使用/usr/local
而不是/usr
。
以下是更正后的内容。
$ cat /usr/local/share/config.site
...
if test -n "$host"; then
# skip when cross-compiling
return 0
fi
if test "$prefix" = /usr/local \
|| { test "$prefix" = NONE && test "$ac_default_prefix" = /usr/local ; }
then
test "$sysconfdir" = '${prefix}/etc' && sysconfdir=/etc
test "$sharedstatedir" = '${prefix}/com' && sharedstatedir=/var
test "$localstatedir" = '${prefix}/var' && localstatedir=/var
ARCH=`uname -m`
for i in x86_64 ppc64 s390x aarch64; do
if test $ARCH = $i; then
test "$libdir" = '${exec_prefix}/lib' && libdir='${exec_prefix}/lib64'
break
fi
done
fi
现在,接下来的问题是,为什么Fedora的/usr/share/config.site
没有正确处理prefix=/usr/local
。这是Issue 1510073 : Autoconf does not honor libdir in config.site for "libdir=@libdir@" in *.pc file的一个悬而未决的问题,已被关闭为 NOT A BUG 。
