I met an error when trying to compile pcre-8.30.tar.gz on Ubuntu 10.04, don't know what is happening.
ciphor@MyUbuntu:~/work/pcre-8.30$ make
make all-am
make[1]: Entering directory `/home/ciphor/work/pcre-8.30'
CXX pcrecpp.lo
libtool: compile: unrecognized option `-DHAVE_CONFIG_H'
libtool: compile: Try `libtool --help' for more information.
make[1]: *** [pcrecpp.lo] Error 1
make[1]:Leaving directory `/home/ciphor/work/pcre-8.30'
make: *** [all] Error 2
I read the Makefile and found the following line:
LTCOMPILE = $(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) \
$(LIBTOOLFLAGS) --mode=compile $(CC) $(DEFS) \
$(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS) \
$(AM_CFLAGS) $(CFLAGS)
wherein $(DEFS) is the "-DHAVE_CONFIG_H" option. I guess it is an option for gcc, not for libtool, right?
It seems that the error is around here, but how to solve it?
Check that g++ is installed, and that the values of CXX, CXXCPP and ac_ct_CXX in the Makefile are set to g++.
