Hi Evan,

I can see a mixture of path styles being printed to screen, did you compile EPICS base from within the msys shell? If that is the case, you may need to run both makeBaseApp and make from inside of the msys shell. If you wish to run these tools outside of msys, you may need to also build epics base outside of msys. It would be interesting to know what make --version says as I think there was an issue with a version of make that did some path appending like you are seeing.

Regards,

Freddie

Hi Evan,

I’m not an MSYS user myself (I’m not keen on the way it uses its own /c/… paths) but there are other people here with more experience of using it who I hope will respond (I think they recommend MSYS2 now though, do you know the difference?). In the meantime some basic questions to provide us with a bit more information:

What version of Base did you install?

Can you try running these commands in your test2 directory and post the results please:

make —version

perl -v

make show-makefiles

make PRINT.MAKE

make PRINT.CONVERTRELEASE

make PRINT.RELEASE_TOPS

Good Afternoon,

I am attempting to get the EPICS build system working on win32-x86 architecture. I have successfully built base, but I get some strange behavior after trying to build an IOC created via makeBaseApp.pl. Here is what I run:

mkdir test2

cd test2

makeBaseApp.pl –t ioc test

makeBaseApp.pl –i –t ioc test

directory structure is now:

-configure

-iocBoot

-testApp

Makefile

configure/RELEASE points at the correct EPICS_BASE

Now, when I try running make, the following output results:

PS C:\Users\daykin\scratch\test2> make

Can't open perl script ".": Permission denied

/c/Users/daykin/scratch/test2/"C:/MinGW/msys/1.0/bin/make.exe" -C ./configure install

/bin/sh: /c/Users/daykin/scratch/test2/C:/MinGW/msys/1.0/bin/make.exe: No such file or directory

make.exe": *** [configure.install] Error 127

See the third line: Somehow, my $(TOP) is prepended to the location of make. It should just be running “C:/MinGW/msys/1.0/bin/make.exe”. I’m not sure if this is also the cause of “Can’t open perl script ‘.’”, which also seems strange.

Is there something I’m missing here?
