Compiling some packages with "-flto -fuse-linker-plugin" gives a libtool error during "make". Compiling the same package without "-flto -fuse-linker-plugin" allows "make" to complete without errors.
Using gcc-4.9.1/binutils-2.24.51 or gcc-5.2.0/binutils-2.25.1 The problem seems to occur with a few 10's of packages (eg cogl-1.20.0), but not with others (eg gnome-music-3.16.2). Using cogl-1.20.0 as an example: CC="gcc -flto -fuse-linker-plugin -mtune=generic -Os -pipe" CXX="g++ -flto -fuse-linker-plugin -mtune=generic -Os -pipe -fno-exceptions -fno-rtti" ./configure --prefix=/usr/local --disable-static --localstatedir=/var --enable-gles1 --enable-gles2 --enable-cogl-gst=yes find . -name Makefile -type f -exec sed -i 's/-g -O2//g' {} \; make ... CC cogl-enum-types.lo CCLD libcogl.la ../libtool: eval: line 1: syntax error: unexpected "|" Makefile:1507: recipe for target 'libcogl.la' failed make[4]: *** [libcogl.la] Error 2 This can be fixed by using NM="gcc-nm", but as binutils was compiled with lto enabled, it shouldn't be required?
