[MITgcm-support] genmake2: going with the flow

[Martin Losch]

Hi,

I am trying to keep up with your pace and want to learn how to use 
genmake2, or is that too early? I am having all sorts of problems:
1. when I specify -optfile=$TOOLSDIR/build_options/linux_ifc I still 
have to specify -fc=ifc to make things work. Is that intended?
2. with the command
 >> ../../tools/genmake2 -optfile=../../tools/build_options/linux_ifc 
-mods=../code -fc=ifc
I get makefile
 >> make depend
... (skipping the usual stuff)
../../tools/f90mkdepend >> Makefile
echo: No match
 >> make
... compile, compile, compile ...
... timer_stats.o -lPEPCF90
make: o: Command not found
make: [mitgcmuv] Error 127 (ignored)
 >>
There's no executable.

3. Apparently there no more .genmakerc. That's too bad, will that 
possibility be put back into genmake2?

4. Do you already have documentation on how to use genmake2. The -help 
option is not that help full. And simple options don't work, e.g.:
 >> ../../tools/genmake2 -mods=../code
....
 >>  make depend
make[1]: Entering directory `/home/lincl/mlosch/head/channel/build2'
../../pkg/debug/chksum_tiled.F chksum_tiled.F
make[1]: execvp: ../../pkg/debug/chksum_tiled.F: Permission denied
make[1]: *** [chksum_tiled.F] Error 127
make[1]: Leaving directory `/home/lincl/mlosch/head/channel/build2'
make: *** [depend] Error 2


If found it hard to understand genmake, but genmake2 is absolutely 
impossible for me to comprehend, so I cannot track down these things 
myself, or include, eg. a .genmakerc switch.
