[Developers] How to build admb source with mingw 64 - finally!

[Jon Schnute]

Johnoel - The build from Rtools worked for me too. I also noticed that you
included the parameter "-m64" in the script "admb.cmd", so that the 64 bit
version of g++ gets invoked in the compile and link steps of when making
*.exe from *.tpl.

 

Would "make CXXFLAGS=-m32 LDFLAGS=-m32" produce 32 bit  code for users with
an older version of Windows? Please reply to this question.

 

Chris, I don't consider our experiments with msys and mingw to be a waste of
time. We actually did get everything working. Also, I note the "make"
command in Rtools doesn't work for building ADMB. (I tried it.) Instead,
Johnoel uses the "utilities\make" function embedded in the ADMB package.
This has unknown origin (to me at least) and lacks modern support.

 

What if R someday changes its approach to Rtools? What if the historical
"utilities\make" fails in some newer environment?

 

Arni, thanks for your recent comments. I'm really glad you joined the
discussion. At some point, I'll pull together some pros and cons associated
with the original MinGW, Rtools, and MinGW-w64. I think the third route
might be safest in the long run. It serves a generic purpose (not just R),
and it has the most dedicated support. 

 

Jon

Johnoel, the rtools 64 build works for me for both release and debug makes.
gdb works for the debug version just fine. Wish I knew it was this easy - I
sure wasted my time messing around with msys and mingw. Never again

For Rtools and 64bit

C:\admb\> utilitites\make CXXFLAGS=-m64 LDFLAGS=-m64

Please svn update
