Telling the configure to use some dir for finding libiconv libraries and headers doesn't get passed to the gcc-subdir. This causes the HAVE_ICONV flag to be set there, but the compilation doesn't find the needed headers (see the attached error message). Manually adding the wanted directory (/usr/local/include) to the INCLUDES in gcc/Makefile allows the compilation to be continued. The compilation fails as follows: --- clip --- gcc -g -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing- prototypes -pedantic -Wno-long-long -fno-common -DHAVE_CONFIG_H -I. -I. - I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include -I../intl \ -DGCC_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386-unknown- freebsd4.8/3.4/include\" - DGPLUSPLUS_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386-unknown- freebsd4.8/3.4/../../../..`echo /home/ppohja/gcc | sed - e 's|^/home/ppohja/gcc||' -e 's|/[^/]*|/..|g'`/include/c++/3.4\" - DGPLUSPLUS_TOOL_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386-unknown- freebsd4.8/3.4/../../../..`echo /home/ppohja/gcc | sed - e 's|^/home/ppohja/gcc||' -e 's|/[^/]*|/..|g'`/include/c++/3.4/i386-unknown- freebsd4.8\" -DGPLUSPLUS_BACKWARD_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386- unknown-freebsd4.8/3.4/../../../..`echo /home/ppohja/gcc | sed - e 's|^/home/ppohja/gcc||' -e 's|/[^/]*|/..|g'`/include/c++/3.4/backward\" - DLOCAL_INCLUDE_DIR=\"/usr/local/include\" - DCROSS_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386-unknown- freebsd4.8/3.4/../../../../i386-unknown-freebsd4.8/sys-include\" - DTOOL_INCLUDE_DIR=\"/home/ppohja/gcc/lib/gcc/i386-unknown- freebsd4.8/3.4/../../../../i386-unknown-freebsd4.8/include\" \ -c ../../gcc/gcc/cppdefault.c -o cppdefault.o gcc -c -g -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing- prototypes -pedantic -Wno-long-long -fno-common -DHAVE_CONFIG_H -I. -I. - I../../gcc/gcc -I../../gcc/gcc/. -I../../gcc/gcc/../include - I../intl ../../gcc/gcc/c-ppoutput.c -o c-ppoutput.o In file included from ../../gcc/gcc/c-ppoutput.c:25: ../../gcc/gcc/cpphash.h:29: iconv.h: No such file or directory gmake[2]: *** [c-ppoutput.o] Error 1 gmake[2]: Leaving directory `/usr/home/ppohja/compile/objdir/gcc' gmake[1]: *** [stage1_build] Error 2 gmake[1]: Leaving directory `/usr/home/ppohja/compile/objdir/gcc' gmake: *** [bootstrap] Error 2 gmake bootstrap 0.44s user 0.48s system 107% cpu 0.847 total
Just to clarify: using --with-libiconv-prefix=/usr/local doesn't cause -I/usr/local/include to be appended to the include flags?
Reminder, this bug is still awaiting feedback. Does /usr/local appear in any of your include paths (can grep through Makefiles to find out...). Thanks.
We know what he wants already, so changing it to NEW.
*** Bug 14431 has been marked as a duplicate of this bug. ***
Situation in "Bug 14431" is different: configure ignores "--with-libiconv-prefix=/usr/local" and HAVE_ICONV is left undefined. Compilation passes, but almost all charset conversions are crippled.
> Does /usr/local appear in any of your include paths > (can grep through Makefiles to find out...). Thanks. FreeBSD 5.1-RELEASE-p11 gcc-3.4-20040303 ../configure --prefix=/usr/local/gcc-20040303-2 --disable-nls --enable-languages=c,c++,java --disable-java-awt --without-x --enable-threads --enable-sjlj-exceptions --with-libiconv-prefix=/usr/local For me the answer is positive. (Although it does not relate with iconv detection problem, IMO). gcc/Makefile: CPPFLAGS = -I/usr/local/include intl/Makefile: CPPFLAGS = -I/usr/local/include i386-unknown-freebsd5.1/libjava/libltdl/Makefile: CPPFLAGS = -O2 -g -O2 -I/usr/local/include i386-unknown-freebsd5.1/libjava/Makefile: CPPFLAGS = -O2 -g -O2 -I/usr/local/include ...
I recently tried to build GCC on FreeBSD-5.2.1 (and with fresh autoconf/automake). GCC is "gcc-3.4-20040303". I have libiconv-1.9.1 port installed (in /usr/local, that is). Configured with: ../configure --prefix=/usr/local/gcc-20040303-4 --disable-nls --enable-languages=c,c++,java --disable-java-awt --without-x --enable-threads=posix --with-libiconv-prefix=/usr/local --with-dwarf2 Here is what I see: intl/config.h - HAVE_ICONV defined! i386-unknown-freebsd5.2.1/libstdc++-v3/config.h - HAVE_ICONV is not defined. i386-unknown-freebsd5.2.1/libjava/include/config.h - HAVE_ICONV is not defined. 8<----------------------->8 ...

I think there's another bug open that's a duplicate of this one, but I can't remember which one right now... possibly bug 78251? Related at least.
