I get this when trying to use libraries: $ emcc -o conftest -I/home/todd/try2/include -L/home/todd/try2/lib conftest.c -lgmp /home/todd/try2/lib/libgmp.so: file not recognized: File format not recognized clang-3.3: error: linker command failed with exit code 1 (use -v to see invocation)
libgmp.so looks like the right type: $ file /home/todd/try2/lib/libgmp.so /home/todd/try2/lib/libgmp.so: LLVM IR bitcode The -v option reveals the culprit: $ emcc -v -o conftest -I/home/todd/try2/include -L/home/todd/try2/lib conftest.c -lgmp clang version 3.3 Target: x86_64-unknown-linux-gnu Thread model: posix "/home/todd/emscripten-fastcomp/build/bin/clang-3.3" -cc1 -triple x86_64-unknown-linux-gnu -emit-obj -mrelax-all -disable-free -disable-llvm-verifier -main-file-name conftest.c -mrelocation-model static -mdisable-fp-elim -fmath-errno -masm-verbose -mconstructor-aliases -munwind-tables -fuse-init-array -target-cpu x86-64 -v -nostdsysteminc -nobuiltininc -resource-dir /home/todd/emscripten-fastcomp/build/bin/../lib/clang/3.3 -D __EMSCRIPTEN__ -D EMSCRIPTEN -I /home/todd/try2/include -fdebug-compilation-dir /home/todd/try2/mpfr-3.1.1 -ferror-limit 19 -fmessage-length 189 -mstackrealign -fobjc-runtime=gcc -fobjc-default-synthesize-properties -fdiagnostics-show-option -fcolor-diagnostics -backend-option -vectorize-loops -nobuiltininc -nostdsysteminc -isystem/home/todd/emscripten/system/local/include -isystem/home/todd/emscripten/system/include/compat -isystem/home/todd/emscripten/system/include -isystem/home/todd/emscripten/system/include/emscripten -isystem/home/todd/emscripten/system/include/bsd -isystem/home/todd/emscripten/system/include/libc -isystem/home/todd/emscripten/system/include/gfx -isystem/home/todd/emscripten/system/include/net -isystem/home/todd/emscripten/system/include/SDL -isystem/home/todd/emscripten/system/include/libcxx -o /tmp/conftest-9LGfCY.o -x c conftest.c clang -cc1 version 3.3 based upon LLVM 3.3svn default target x86_64-unknown-linux-gnu ignoring nonexistent directory "/home/todd/emscripten/system/local/include" ignoring nonexistent directory "/home/todd/emscripten/system/include/bsd" ignoring nonexistent directory "/home/todd/emscripten/system/include/net" #include "..." search starts here: #include <...> search starts here: /home/todd/try2/include /home/todd/emscripten/system/include/compat /home/todd/emscripten/system/include /home/todd/emscripten/system/include/emscripten /home/todd/emscripten/system/include/libc /home/todd/emscripten/system/include/gfx /home/todd/emscripten/system/include/SDL /home/todd/emscripten/system/include/libcxx End of search list.

This is a fresh checkout of emscripen, emscripten-fastcomp, and emscripten-fastcomp-clang running on Ubuntu 14.04. Did I miss a key step in the build instructions?
