Compiling NSIS with MinGW in Windows?

I tried to compile NSIS with MinGW gcc but I got following error:

G:\NSIS>scons TOOLSET=gcc UNICODE=yes

scons: Reading SConscript files ...

  File "c:\Python27\Lib\site-packages\scons-2.3.0\SCons\SConf.py", line 611:

how can I fix it?

I know compiling with MinGW works so the problem is probably with scons, try scons 2.0 or 1.3?

I don't remember which version I'm using, 1.2 maybe. New scons versions tends to break things so I refuse to upgrade.

I tried 1.2.0 but with same result:

G:\NSIS>scons-1.2.0.bat TOOLSET=gcc UNICODE=yes

And if you remove TOOLSET=gcc?

I'll take a look at which scons version I'm using and the command line tomorrow...

I'm using scons 1.2 but not TOOLSET=gcc, it should be able to find the compiler by looking in %path%

alright I think I found a way to force scons to use gcc instead of my old vc2003 compiler.

scons TOOLSET=gcc,gnulink,mingw UNICODE=yes "PATH=%PATH%" dist 2>&1|tee scon.log

but I wonder if gcc-4.6.3 is not new enough for compiling NSIS?
I got error when compiling script.c:

scons: *** [build\urelease\makensis\script.o] Error 1

scons: building terminated because of errors.

I've been testing and debugging the linux build using gcc, and I haven't seen this error before. I can't really help though as I use VS2008 for windows compiling.

We have a macro called COUNTOF and it tries to use the version in the compiler if possible but I guess gcc is unable to handle anonymous structs. You can try to force our custom version of COUNTOF by removing the #ifdef __countof part...
