Bug ID: 88715
Summary: Cross Compile on Debian Linux to create a uClibc tool
chain GCC fails to compile
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tomsies at mighty dot co.za
Target Milestone: ---
System is Debian Linux (Debian 3.16.36-1+deb8u2 (2016-10-19) x86_64 GNU/Linux)
I have compiled uClibc-ng-1.0.31 using linux headers LinuxHeaders-2.6.32.25
This is installed in /opt/uCx
I try to build a cross compiler targeting this libc as follows
../gnuSource/gcc-8.2.0/configure --prefix=/opt/uCx --with-sysroot=/opt/uCx
--with-pkgversion=DDT --disable-bootstrap --target=i686-uClibc-linux
--enable-shared=no --disable-lto-plugin --disable-libsanitizer
--disable-boehm-gc --disable-libmudflap --disable-libgcj
--enable-languages=c,c++,fortran,lto,objc,obj-c++ --enable-libstdcxx-time
--enable-libstdcxx-threads --with-host-libstdcxx='-static -lstdc++ -lm'
--with-boot-ldflags='-static-libstdc++ -static-libgcc'
As soon as the compile starts to build i686-uClibc-linux objects configure
fails as below
configure:3687: /src/abuild/./gcc/xgcc -B/src/abuild/./gcc/
-B/opt/uCx/i686-uClibc-linux/bin/ -B/opt/uCx/i686-uClibc-linux/lib/ -isystem
/opt/uCx/i686-uClibc-linux/include -isystem

configure:3705: error: in `/src/abuild/i686-uClibc-linux/libgcc':
configure:3708: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
What the issue seems to be is that the x-compile in GCC has built a script to
replace the as command using exec. This script is using exec without proper
quoting so exec is trying to exec --32 as well as as
/src/abuild/./gcc/as --32 -o conftest.o /tmp/ccE1mSpa.s
