Re: GCJ Build Error

[Antonio Ake <ake at ecn dot purdue dot edu>]

I have recorded most of the changes that I have done from the release of
July 2nd, 2001. I hope this help. I am working with a Tru64 Unix v5.0 910
I have noticed some unique problems for this version of Tru64 UNIX, like
the natPlainDatagramsocket.cc.


1. libstdc++V3 config error building GCC 3.0 on alphaev6-dec-osf5.0
Reference: http://gcc.gnu.org/ml/libstdc++/2001-06/msg00507.html
Solution: http://gcc.gnu.org/ml/libstdc++/2001-07/msg00039.html

2. Invalid instruction " imb" on  Alpha
Reference: http://gcc.gnu.org/ml/gcc/2001-06/msg01527.html
Solution:  http://gcc.gnu.org/ml/gcc-patches/2001-07/msg00873.html

3. undefined assembler operation: .section  .section .rodata
Reference and Solution: http://gcc.gnu.org/ml/gcc-patches/2001-06/msg01564.html


4. natfile.cc" didn't compile because of duplicate of stat.
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00165.html
Solution: http://gcc.gnu.org/ml/java/2001-07/msg00163.html

5. _ZN4java4lang5ClassC1Ev multiple defined in Alpha OSF1
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00167.html
Solution: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00024.html

6. Object file format error in Alpha OSF1
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00172.html
This is a problem with the Tru64 UNIX OSF1 version 5.0 linker problem:
http://ftp1.support.compaq.com/public/unix/v5.0/Tru64_UNIX_V5.0/
Patch 578.00   OSF500-364. The patch was not installed, but to reduce the size of the libgcj, the java.awt libraries were omitted using the following command in gcc configure:
"configure -without-x "

7. natPlainDatagramSocketImpl.cc doesn't compile in ALPHA OSF1.
Reference GNAT PR 3694 on http://gcc.gnu.org
Solution: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00181.html

8. natPlainSocketImpl.cc doesn't compile on ALPHA OSF1
Reference GNAT PR 3696 on http://gcc.gnu.org
Solution: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00181.html

9. Problem with Alpha OSF1 and mips-tfile
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00188.html
Solution: http://gcc.gnu.org/ml/java/2001-07/msg00188.html

10.Due to the Problem with Alpha OSF1 and mips-tfile, I compile by hand HelloWorld.java, but I had a segmentation fault:
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00197.html
Solution: Order of the library in the collect2 command -lgcc_s -lgcc -lgcj -lm -lgcjgc -lzgcj -lgcc_s -lgcc -lc -lgcc_s -lgcc

11. "iconv" library problem:
Reference: http://gcc.gnu.org/ml/java/2001-07/msg00209.html
Solution: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00124.html


12. symbol "JNI_OnLoad" unresolved
Reference: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00128.html
Solution: http://gcc.gnu.org/ml/java-patches/2001-q3/msg00207.html

13. internal error with a classbyte file Reference
http://gcc.gnu.org/ml/java/2001-07/msg00222.html
Workaround: compile this program with  -O option.
