I'm having trouble compiling crypto-related libraries on MacOSX and OpenBSD, since it requires:
CFLAGS="-I/usr/local/include" LDFLAGS="-I/usr/local/lib" to be passed in the environment. Our "conf-gmp" package currently just does a "cc -c gmp.c" which is very unlikely to work portably. I was trying to modify the package description to use CFLAGS passed in externally to the `opam` command-line, and this diff works: diff --git a/packages/conf-gmp/conf-gmp.1/opam b/packages/conf-gmp/conf-gmp.1/opam index d0f0065..8b45586 100644 --- a/packages/conf-gmp/conf-gmp.1/opam +++ b/packages/conf-gmp/conf-gmp.1/opam @@ -2,7 +2,7 @@ opam-version: "1" maintainer: "nbraud" homepage: "http://gmplib.org/" license: "GPL" -build: [["cc" "-c" "test.c"]] +build: [["sh" "-c" "cc -c $CFLAGS test.c"]] depexts: [ [["debian"] ["libgmp-dev"]] [["ubuntu"] ["libgmp-dev"]] However, is there a better way to pass through environment variables to OPAM packages? An %{env:CFLAGS}% macro would be cleaner than forcing evaluation through a subshell as my diff above does. -anil _______________________________________________ opam-devel mailing list [email protected] http://lists.ocaml.org/listinfo/opam-devel
