Hello all! I wanted to compile a helloworld program with selfcompiled gcc-3.4.3 (see below for more info). It had linking problems. Compile only works fine. The program was: // Begin of Test.java import java.lang.*; class Test { public static void main(String args[]) { System.out.println("Hello world.\n"); } }; // EOF The gcj call and output was: gcj Test.java /usr/lib/crt1.o: In function `_start': /usr/lib/crt1.o(.text+0x18): undefined reference to `main' collect2: ld returned 1 exit status I tried gcc, which gave some additional info: gcc Test.java /usr/lib/crt1.o: In function `_start': /usr/lib/crt1.o(.text+0x18): undefined reference to `main' /tmp/ccq72aMH.o: In function `Test::main(JArray<java::lang::String*>*)': /tmp/ccq72aMH.o(.text+0x8): undefined reference to `java::lang::System::class$' /tmp/ccq72aMH.o(.text+0x1b): undefined reference to `_Jv_InitClass' /tmp/ccq72aMH.o(.text+0x28): undefined reference to `java::lang::System::class$' /tmp/ccq72aMH.o(.text+0x2d): undefined reference to `_Jv_InitClass' /tmp/ccq72aMH.o(.text+0x37): undefined reference to `java::lang::System::out' /tmp/ccq72aMH.o: In function `Test::Test()': /tmp/ccq72aMH.o(.text+0x5f): undefined reference to `java::lang::Object::Object()' /tmp/ccq72aMH.o(.data+0x50): undefined reference to `java::lang::Object::finalize()' /tmp/ccq72aMH.o(.data+0x54): undefined reference to `java::lang::Object::hashCode()' /tmp/ccq72aMH.o(.data+0x58): undefined reference to `java::lang::Object::equals(java::lang::Object*)' /tmp/ccq72aMH.o(.data+0x5c): undefined reference to `java::lang::Object::toString()' /tmp/ccq72aMH.o(.data+0x60): undefined reference to `java::lang::Object::clone()' /tmp/ccq72aMH.o(.data+0xa0): undefined reference to `vtable for java::lang::Class' /tmp/ccq72aMH.o(.data+0xb4): undefined reference to `java::lang::Object::class$' /tmp/ccq72aMH.o(.eh_frame+0x11): undefined reference to `__gcj_personality_v0' collect2: ld returned 1 exit status My gcc was compiled with this config: gcc -v Reading specs from /usr/local/gcc343/lib/gcc/i686-pc-linux-gnu/3.4.3/specs Configured with: ../gcc-3.4.3/configure --prefix=/usr/local/gcc343 --enable-threads=posix --enable-__cxa_atexit --enable-version-specific-runtime-libs --enable-languages=c,c++,f77,objc,java --enable-gather-detailed-mem-stats --enable-nls --with-included-gettext --enable-interpreter --enable-libgcj-multifile --with-x --enable-java-awt=xlib Thread model: posix gcc version 3.4.3 I've got an i686 athlon (k7) machine with SuSE 8.1 glibc-2.2.5 (the crt1.o is in that package). I looked into the crt1.o with nm, here's the small output: nm /usr/lib/crt1.o 00000004 R _IO_stdin_used 00000000 D __data_start U __libc_start_main U _fini 00000000 R _fp_hw U _init 00000000 T _start 00000000 W data_start U main Can anyone help me? Did I forget to install/update something? How about environment variables anything SPECIAL I need?
