Can't compile under mingw 64-bit anymore

[robe]

I'm going to try recompiling 2.0.0 to make sure its not something that has changed in my environment, but 2.0.1 doesn't compile — gives this error:

My mingw 3.4.5 32-bit still compiles okay

forgot to mention this is using r9653 and I did do an sh autogen.sh and a make clean

[robe]

I've confirmed. The postgis 2.0.0 tagged compiles fine for me but 2.0.1 does not.

Okay I isolated the issue to our use of SQLPP.

On my mingw 32-bit

postgis/makefile SQLPP = /mingw/bin/cpp -traditional-cpp -P

but my mingw 64-bit SQLPP =

So I guess it doesn't know how to properly handle the:

$(SQL_OBJS): %.in: %.in.c
	$(SQLPP) -I../libpgcommon $< | grep -v '^#' > $@

in http://trac.osgeo.org/postgis/browser/trunk/postgis/Makefile.in#L135

Right so the culprit must be this commit: http://trac.osgeo.org/postgis/changeset/9639/.

What does typing just "cpp" at the MingW terminal give you on both 32-bit and 64-bit? I'm guessing that perhaps it doesn't exist on 64-bit.

Mark,

I figured out how to fix so I'm going to close this out. I suspect it is only an issue with cross-compilers. I'm not sure how to make it pick it up right, I think it does for other executables.

The issue is that in my c:\ming64\mingw64\bin the file is called:

x86_64-w64-mingw32-cpp.exe

If I copy this striping off the version so I have just a cpp.exe

It picks it up fine and compiles fine. Still doing my make check.

I suspect I may just have to note this in the wiki on compiling under mingw64, because some mingw64 have the executables already stripped and some do not so might work for one person out of the box and not another. I've had to do this with one other exe. Can't remember which one off hand.
