You might be getting caught by some arcane setup logic with dependencies. I'd recommend uninstalling all gcc packages and then reinstall all the ones you need together. That should get you the versions you want.
That made sense, and I tried it, but I was unable to get all the gcc packages uninstalled. I could remove most of them, but upon trying to remove the last one, setup would crash.
What I tried was to get all the components at version 3.3.3-3, which worked ok, and then to replace them all with version 3.4.1-1. I could get most of it, but I could not get rid of this error message:
$ gcj Hello.java
/usr/lib/gcc/i686-pc-cygwin/3.4.1/../../../../i686-pc-cygwin/bin/ld: cannot find -lgcc
Looking through gcj --help, I found the following option:
$ gcj -print-libgcc-file-name libgcc.a
Doing a search for libgcc.a at http://cygwin.com/packages/ I found that it should be in one of the following packages:
gcc/gcc-3.3.1-1 gcc/gcc-3.3.1-3 gcc-core/gcc-core-3.3.3-3 gcc-core/gcc-core-3.4.1-1
The only 3.4.1-1 version there is the package gcc-core. But it looks like gcc-core is only source files. In any case, installing it doesn't product libgcc.a.
However, look closely at the path in the error message:
/usr/lib/gcc/i686-pc-cygwin/3.4.1/
I don't think i686-pc-cygwin is what I want. I'm trying to create a win32 binary. I need to use -mno-cygwin on the gcj command line! Now I get:
$ gcj -mno-cygwin Hello.java
/usr/lib/gcc/i686-pc-mingw32/3.4.1/../../../../i686-pc-mingw32/bin/ld: cannot find -lgcc
At some point I had libgcj.a installed in i686-pc-mingw32. Unfortunately, it went away. Now let me see if I can get it back.
Just now I see that Yitzchak Scott-Thoennes wrote:
Don't mess with the version numbers it shows you. Use the ones it shows when the Curr(ent) radio button is selected or the ones it shows when the Exp(erimental) radio button is selected.
That looks like it might work. Before I saw that, I had dropped back again to 3.3.3-3. With the experimental button selected, I setup wants to install version 3.4.1-1 for gcc, gcc-core, gcc-g++ and gcc-java. gcc-mingw it wants to keep at 20040810-1. It wants to install 20040822-1 for gcc-mingw-core, gcc-mingw-g++, and gcc-mingw-java.
(Hopefully, he presses the Next button... Installation complete...)
$ gcj -mno-cygwin Hello.java /usr/lib/gcc/i686-pc-mingw32/3.4.1/../../../../i686-pc-mingw32/lib/libmingw32.a( main.o)(.text+0x106):main.c: undefined reference to [EMAIL PROTECTED]'
Well that's progress.
$ gcj -mno-cygwin Hello.java -lm
Nope. Try "man gcj":
$ gcj -mno-cygwin --main=Hello Hello.java gcj: installation problem, cannot exec 'cc1': No such file or directory
I did "download from internet", selected the Exp button, and now the installer wants to download the binary for gcc-core 3.4.1-1. I thought there was just source. Must have missed that before...
$ gcj -mno-cygwin --main=Hello Hello.java
[EMAIL PROTECTED] ~/IrateDev/Hello $ ls Hello.java a.exe
[EMAIL PROTECTED] ~/IrateDev/Hello $ ./a.exe Hello, World!
Now to checkout the iRATE sources. Taras Glek managed to built iRATE with gcj for Win32 last night, but I think he was doing the builds on Linux.
Success!
Thanks for your help, I appreciate it.
