GCJ and ARM-ELF not cross compilable to native code Hello,
we compiled and installed gcj for i686 not cross. It worked fine. We compiled and installed gcj for arm-elf cross. It produced .class-files. We were not able to compile and install gcj for arm-elf cross to produce native code. We checked different combinations of versions of gcc, gcc-core, newlib and binutils. The "newest" combination that works is binutils-2.14 gcc-3.3.1 with gcc-core-3.3.1 newlib-1.11 For building we used the script found at http://www.zingo.org/handheld/build-crossgcc.sh originally by Bill Gatliff. We received the following error message when compiling gcc-3.3.1 for arm as cross producing native: ... ava/.././libjava/../gcc -I../../../../gcc-3.3.1/libjava/../zlib -fno-rtti -fnon-call-exceptions -fdollars-in-identifiers -Wswitch-enum -I/usr/X11/include -W -Wall -D_GNU_SOURCE -DPREFIX=\"/home/mdeuli/armgcc2/arm-elf\" -g -O2 -mthumb -MD -MT java/io/natFile.lo -MF java/io/natFile.pp -c java/io/natFile.cc -o java/io/natFile.o java/io/natFile.cc: In member function `jboolean java::io::File::_access(__java_int)': java/io/natFile.cc:54: error: `::access' undeclared (first use here) java/io/natFile.cc: In member function `virtual java::lang::String* java::io::File::getCanonicalPath()': java/io/natFile.cc:111: warning: unused variable `char buf2[((MAXPATHLEN - 1) + 1)]' java/io/natFile.cc: In member function `JArray<java::lang::Object*>* java::io::File::performList(java::io::FilenameFilter*, java::io::FileFilter*, java::lang::Class*)': java/io/natFile.cc:142: warning: unused parameter ` java::io::FilenameFilter*filter' java/io/natFile.cc:142: warning: unused parameter ` java::io::FileFilter*fileFilter' java/io/natFile.cc:142: warning: unused parameter ` java::lang::Class*result_type' java/io/natFile.cc: In member function `jboolean java::io::File::performSetLastModified(__java_long)': java/io/natFile.cc:261: warning: unused parameter `jlong time' java/io/natFile.cc: In member function `jboolean java::io::File::performCreate()': java/io/natFile.cc:294: error: `::close' undeclared (first use here) java/io/natFile.cc: In member function `jboolean java::io::File::performDelete()': ... We checked different scripts and compiler versions until gcc-4.0.0. The above mentioned combination is the one that proceeded furtherest. Building gcc-core succeeded so we now have a arm-elf-gcj cross compiler without libgcj. We tried to compile java source using this cross compiler and a libgcj-3.3.4.jar using --CLASSPATH. That produced following error message: [EMAIL PROTECTED]:~/gcjtest> ~/armgcc2/armelf4/bin/arm-elf-gcj --CLASSPATH=./libgcj-3.3.4.jar -shared --main=Test Test.java -o Test /home/mdeuli/armgcc2/armelf4/bin/../lib/gcc/arm-elf/3.4.4/../../../../arm-elf/lib/crt0.o: In function `start': : undefined reference to `memset' /home/mdeuli/armgcc2/armelf4/bin/../lib/gcc/arm-elf/3.4.4/../../../../arm-elf/lib/crt0.o: In function `start': : undefined reference to `initialise_monitor_handles' /home/mdeuli/armgcc2/armelf4/bin/../lib/gcc/arm-elf/3.4.4/../../../../arm-elf/lib/crt0.o: In function `start': : undefined reference to `exit' /tmp/cc2flY8E.o: In function `main': cckq7EG0.i:(.text+0x30): undefined reference to `JvRunMain' cckq7EG0.i:(.text+0x40): undefined reference to `_Jv_Compiler_Properties' /tmp/ccINY1tl.o: In function `Test::main(JArray<java::lang::String*>*)': Test.java:(.text+0x38): undefined reference to `_Jv_InitClass' Test.java:(.text+0x4c): undefined reference to `_Jv_InitClass' Test.java:(.text+0xa0): undefined reference to `java::lang::System::class$' Test.java:(.text+0xa8): undefined reference to `java::lang::System::out' /tmp/ccINY1tl.o: In function `Test::Test()': Test.java:(.text+0xcc): undefined reference to `java::lang::Object::Object()' /tmp/ccINY1tl.o:(.data+0x38): undefined reference to `java::lang::Object::finalize()' /tmp/ccINY1tl.o:(.data+0x3c): undefined reference to `java::lang::Object::hashCode()' /tmp/ccINY1tl.o:(.data+0x40): undefined reference to `java::lang::Object::equals(java::lang::Object*)' /tmp/ccINY1tl.o:(.data+0x44): undefined reference to `java::lang::Object::toString()' /tmp/ccINY1tl.o:(.data+0x48): undefined reference to `java::lang::Object::clone()' /tmp/ccINY1tl.o:(.data+0x70): undefined reference to `vtable for java::lang::Class' /tmp/ccINY1tl.o:(.data+0x84): undefined reference to `java::lang::Object::class$' collect2: ld returned 1 exit status We need native arm-elf code produced by gcj. Does anyone know a solution to really produce that code ?
