Re: Windows static build

["Johnson, Andrew N. via Tech-talk" <tech-talk@aps.anl.gov>]

Hi Patrick,

Not sure if you did this, but on Windows you always have to pair setting STATIC_BUILD=YES with SHARED_LIBRARIES=NO, or use the windows-x64-static target architecture (set EPICS_HOST_ARCH to that before compiling if you weren’t setting it at all before). The advantage of using the -static target arch is that you can have both architectures built in the same Base tree and use them for different IOCs.

HTH,

Hello,

I created an example IOC with the following commands on Windows 10 and successfully compiled it with gmake:

../../base-7.0/bin/windows-x64/makeBaseApp.pl -t example ads

../../base-7.0/bin/windows-x64/makeBaseApp.pl -i -a windows-x64 -t example example

I then added STATIC_BUILD=YES to the CONFIG_SITE file, ran gmake distclean, and tried to compile it again. This time the compilation failed with this error:

Would someone happen to know what I might be doing wrong?

Thank you,
