Bug #: 56412
Summary: [4.8 Regression] "libtool: cygpath: command not found"
for mingw32 host
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: daniel.f.sta...@freenet.de
Configuring gcc r196092 for mingw32 on ming32 host without bootstrapping it
failed at lto-plugin for libtool with the following configuration:
../gcc-4.8/configure --enable-languages=c --disable-sjlj-exceptions
--disable-nls --disable-shared --enable-static --enable-fully-dynamic-string
--enable-libgomp --enable-lto --with-dwarf2 --disable-win32-registry
--enable-version-specific-runtime-libs --disable-bootstrap --build=mingw32
--enable-abi=32 --enable-checking=release --with-mpfr=/mingw --with-gmp=/mingw
--with-mpc=/mingw --prefix=/mingw
The error message for "make all-gcc" is:
make[2]: Entering directory `/new-gcc/bin/lto-plugin'
/bin/sh ./libtool --tag=CC --tag=disable-static --mode=compile gcc

with the following values assigned:
srcfile: ../../gcc-4.8/lto-plugin/lto-plugin.c
fix_srcfile_path: `cygpath -w "$srcfile"`
The problem is probably within libtool.m4 where fix_srcfile_path is assigned
with cygpath even for mingw host at line 4790 with:
_LT_TAGVAR(fix_srcfile_path, $1)='`cygpath -w "$srcfile"`'
