On Manjaro Linux 17, installed from manjaro-kde-17.1.12-stable-x86_64.iso, it is possible to build 64-bit binaries (with CC="gcc") or 32-bit binaries (with CC="gcc -m32").
With CC="gcc -32", the compilation fails: $ make ... gcc -m32 -I/usr/include/guile/2.2 -pthread -g -O2 -Wl,--export-dynamic -L/home/bruno/prefix32/lib -o make src/ar.o src/arscan.o src/commands.o src/default.o src/dir.o src/expand.o src/file.o src/function.o src/getopt.o src/getopt1.o src/guile.o src/hash.o src/implicit.o src/job.o src/load.o src/loadapi.o src/main.o src/misc.o src/output.o src/read.o src/remake.o src/rule.o src/shuffle.o src/signame.o src/strcache.o src/variable.o src/version.o src/vpath.o src/posixos.o src/remote-stub.o -lguile-2.2 -lgc lib/libgnu.a -ldl /bin/ld: skipping incompatible /usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../libguile-2.2.so when searching for -lguile-2.2 /bin/ld: skipping incompatible /usr/lib/libguile-2.2.so when searching for -lguile-2.2 /bin/ld: cannot find -lguile-2.2 /bin/ld: skipping incompatible /usr/lib/gcc/x86_64-pc-linux-gnu/8.2.0/../../../libgc.so when searching for -lgc /bin/ld: skipping incompatible /usr/lib/libgc.so when searching for -lgc /bin/ld: cannot find -lgc collect2: error: ld returned 1 exit status make[1]: *** [Makefile:821: make] Error 1 The cause: libguile-2.2.so happens to be installed only as 64-bit binaries, in /usr/lib. Not as 32-bit binaries, in /usr/lib32. Yet, /usr/include/guile/2.2/ exists. The configuration has produced incorrect results: ... checking for GNU Guile... 2.2 checking for GUILE... yes checking for libguile.h... yes ... The first two among these findings are wrong, since /usr/lib32/libguile.* does not exist. $ grep GUILE config.status S["HAVE_GUILE_FALSE"]="#" S["HAVE_GUILE_TRUE"]="" S["GUILE_LIBS"]="-lguile-2.2 -lgc " S["GUILE_CFLAGS"]="-I/usr/include/guile/2.2 -pthread " D["HAVE_GUILE"]=" 1" These five values are all wrong.
