Hi all, Trying to build ruby and lua extensions from freeswitch/libs/esl: lua]$ make g++ -Wno-unused-function -c esl_wrap.cpp -o esl_wrap.o esl_wrap.cpp:1510:17: fatal error: esl.h: No such file or directory compilation terminated. make: *** [esl_wrap.o] Error 1 this can be fixed adding -I../src/include to esl_wrap.o task but has ld error then: lua]$ make g++ -Wno-unused-function -I../src/include -c esl_wrap.cpp -o esl_wrap.o g++ esl_wrap.o -llua -lpthread -o ESL.so -L. /usr/lib/gcc/i686-pc-linux-gnu/4.7.0/../../../crt1.o: In function `_start': (.text+0x18): undefined reference to `main' esl_wrap.o: In function `_wrap_new_ESLevent__SWIG_0': esl_wrap.cpp:(.text+0x3974): undefined reference to `ESLevent::ESLevent(char const*, char const*)' esl_wrap.o: In function `_wrap_new_ESLevent__SWIG_1': ... (tl;dr) Same with ruby (even worse), it was failing to find ruby.h and ruby/config.h. I got make esl_wrap.cpp task fixed http://pastebin.com/uKFBZVF3 but there's an ld error again: $ make g++ esl_wrap.o -lpthread -lrt -ldl -lcrypt -lm -L. -rdynamic -Wl,-export-dynamic -o ESL.so -L. /usr/lib/gcc/i686-pc-linux-gnu/4.7.0/../../../crt1.o: In function `_start': (.text+0x18): undefined reference to `main' esl_wrap.o: In function `rb_class_of': esl_wrap.cpp:(.text+0x9ed): undefined reference to `rb_cFixnum' esl_wrap.cpp:(.text+0x9fa): undefined reference to `rb_cTrueClass' Anyone successful with this stuff? I'm not experienced with GCC stuff at all. It would be very nice to pack this Ruby ESL to a gem (ruby package manager). BR, Phil
