From: David Bremner <bremner@debian.org> Carl reports "gcc -aux-info notmuch.aux lib/notmuch.h" does not generate notmuch.aux for him with Debian gcc 4.6.0-8. Based on a suggestion by Austin Clements, this version uses objdump to get the symbols from the object files. Any symbol that - is in some object file in $(libnotmuch_modules), and - starts with notmuch_ will be exported. --- Here is another way of doing this, probably better unless you are very attached to the idea of declaring the API in the header file. lib/Makefile.local | 7 +++---- 1 files changed, 3 insertions(+), 4 deletions(-) diff --git a/lib/Makefile.local b/lib/Makefile.local index a33ba34..38913c6 100644 --- a/lib/Makefile.local +++ b/lib/Makefile.local @@ -75,10 +75,9 @@ $(dir)/$(LIBNAME): $(libnotmuch_modules) notmuch.sym echo $(libnotmuch_modules) $(call quiet,CXX $(CXXFLAGS)) $(libnotmuch_modules) $(FINAL_LIBNOTMUCH_LDFLAGS) $(LIBRARY_LINK_FLAG) -o $@ -notmuch.sym: lib/notmuch.h - gcc -aux-info notmuch.aux $< +notmuch.sym: $(libnotmuch_modules) printf "{\nglobal:\n" > notmuch.sym - sed -n 's/.*\(notmuch_[a-z_]*\) (.*/\t\1;/p' notmuch.aux >> notmuch.sym + objdump -t $(libnotmuch_modules)| awk '$$4 == ".text" && $$6 ~ "^notmuch" {print "\t"$$6";"}' >>notmuch.sym printf "local: *;\n};\n" >> notmuch.sym $(dir)/$(SONAME): $(dir)/$(LIBNAME) @@ -103,4 +102,4 @@ install-$(dir): $(dir)/$(LIBNAME) $(LIBRARY_INSTALL_POST_COMMAND) SRCS := $(SRCS) $(libnotmuch_c_srcs) $(libnotmuch_cxx_srcs) -CLEAN := $(CLEAN) $(libnotmuch_modules) $(dir)/$(SONAME) $(dir)/$(LINKER_NAME) $(dir)$(LIBNAME) libnotmuch.a notmuch.aux notmuch.sym +CLEAN := $(CLEAN) $(libnotmuch_modules) $(dir)/$(SONAME) $(dir)/$(LINKER_NAME) $(dir)$(LIBNAME) libnotmuch.a notmuch.sym -- 1.7.5.4
