Hm, this build was not "merged" with binutils, nor winsup/cygwin. Fixed by adding -lc and -lpthread, and being sure to do so before -lkernel32. Or maybe a merged tree will do. I know I know, 1) that's a heck of a gnarly configure line 2) mainly just missing "libc" in there, somehow. To be investigated... or I could just do -disable-share or -without-share=gcc or whatever.. which would also fix a problem on Solaris where 32bit and 64bit library paths get confused... and then from a 4.3.2 slightly patched tree: libtool: compile: /obj/gcc.4/./gcc/xgcc -shared-libgcc -B/obj/gcc.4/./gcc -nost dinc++ -L/obj/gcc.4/i686-pc-cygwin/libstdc++-v3/src -L/obj/gcc.4/i686-pc-cygwin/ libstdc++-v3/src/.libs -L/obj/gcc.4/i686-pc-cygwin/winsup -L/obj/gcc.4/i686-pc-c ygwin/winsup/cygwin -L/obj/gcc.4/i686-pc-cygwin/winsup/w32api/lib -isystem /src/ gcc/winsup/include -isystem /src/gcc/winsup/cygwin/include -isystem /src/gcc/win sup/w32api/include -nostdinc -B/obj/gcc.4/i686-pc-cygwin/newlib/ -isystem /obj/g cc.4/i686-pc-cygwin/newlib/targ-include -isystem /src/gcc/newlib/libc/include -B /usr/local/i686-pc-cygwin/bin/ -B/usr/local/i686-pc-cygwin/lib/ -isystem /usr/lo cal/i686-pc-cygwin/include -isystem /usr/local/i686-pc-cygwin/sys-include -L/obj /gcc.4/./ld -DHAVE_CONFIG_H -I. -I/src/gcc/libjava -I./include -I./gcj -I/src/gc c/libjava -Iinclude -I/src/gcc/libjava/include -I/src/gcc/libjava/classpath/incl ude -Iclasspath/include -I/src/gcc/libjava/classpath/native/fdlibm -I/src/gcc/li bjava/../boehm-gc/include -I../boehm-gc/include -I/src/gcc/libjava/.././libjava/ ../gcc -I/src/gcc/libjava/../zlib -I/src/gcc/libjava/../libffi/include -I../libf fi/include -fno-rtti -fnon-call-exceptions -fdollars-in-identifiers -Wswitch-enu m -D_FILE_OFFSET_BITS=64 -ffloat-store -fomit-frame-pointer -Usun -Wextra -Wall -D_GNU_SOURCE -DPREFIX=\"/usr/local\" -DTOOLEXECLIBDIR=\"/usr/local/lib/gcc/i686 -pc-cygwin/4.3.2\" -DJAVA_HOME=\"/usr/local\" -DBOOT_CLASS_PATH=\"/usr/local/sha re/java/libgcj-4.3.2.jar\" -DJAVA_EXT_DIRS=\"/usr/local/share/java/ext\" -DGCJ_E NDORSED_DIRS=\"/usr/local/share/java/gcj-endorsed\" -DGCJ_VERSIONED_LIBDIR=\"/us r/local/lib/gcj-4.3.2-9\" -DPATH_SEPARATOR=\":\" -DECJ_JAR_FILE=\"\" -DLIBGCJ_DE FAULT_DATABASE=\"/usr/local/lib/gcj-4.3.2-9/classmap.db\" -DLIBGCJ_DEFAULT_DATAB ASE_PATH_TAIL=\"gcj-4.3.2-9/classmap.db\" -O2 -g -g -O2 -MT java/net/natVMInetAd dress.lo -MD -MP -MF java/net/.deps/natVMInetAddress.Tpo -c java/net/natVMInetAd dress.cc -DDLL_EXPORT -DPIC -o java/net/.libs/natVMInetAddress.o java/net/natVMInetAddress.cc:42: error: declaration of C function 'int gethostna me(char*, int)' conflicts with /src/gcc/newlib/libc/include/sys/unistd.h:227: error: previous declaration 'int gethostname(char*, size_t)' here make[3]: *** [java/net/natVMInetAddress.lo] Error 1 make[3]: Leaving directory `/obj/gcc.4/i686-pc-cygwin/libjava' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/obj/gcc.4/i686-pc-cygwin/libjava' make[1]: *** [all-target-libjava] Error 2 make[1]: Leaving directory `/obj/gcc.4' make: *** [all] Error 2 [EMAIL PROTECTED] /obj/gcc.4 $ more /obj/gcc.4/config.log $ /src/gcc/configure -disable-nls STAGE_CC_WRAPPER=ccache -prefix=/usr/local - exec-prefix=/usr/local -libdir=/usr/local/lib -libexecdir=/usr/local/lib -mandir =/usr/local/share/man -infodir=/usr/local/share/info -enable-languages=c,c++,for tran,java,objc,obj-c++ -disable-nls -without-included-gettext -enable-version-sp ecific-runtime-libs -without-x -enable-libgcj -disable-java-awt -with-system-zli b -enable-interpreter -disable-libgcj-debug -enable-threads=posix -enable-java-g c=boehm -disable-win32-registry -enable-sjlj-exceptions -enable-hash-synchroniza tion -enable-libstdcxx-debug Probably the right fix here is some configury to look for the declaration of gethostname and if it is found, be sure to #include where it is found, and not declare it one's self? - Jay
