Re: areadetector on windows, xml2

[Mark Rivers via Tech-talk <tech-talk@aps.anl.gov>]

Hi William,

Your error is coming when building the nanohttp_stream.dll.  That depends on xml2.lib, which is built earlier in that same Makefile if XML2_EXTERNAL is defined to be NO.

https://github.com/areaDetector/ADSupport/blob/ac5d261a1abcddba11827a0b5ce500437e4485c9/supportApp/xml2Src/Makefile#L23

2 questions:

• Is XML2_EXTERNAL defined to be NO in areaDetector/configure/CONFIG_SITE.local?
• Just before you get that error do you see xml2.lib being built?  Does it exist in the ADSupport/lib/windows-x64 directory?

Mark

Subject: areadetector on windows, xml2

 

I would like to use areadetector on windows, in combination with
Princeton Lightfield Software.
when compiling ADSupport, it fails with an error regarding xml2 library.

make[3]: Entering directory
'C:/EPICS/epics-support/areaDetector/ADSupport/supportApp/xml2Src/O.windows-x64'
link -nologo -subsystem:windows -dll -LTCG -incremental:no -opt:ref

the manual states that since R2-5, the support package holds source code
for xml2 lib.
clearly, it tries to compile but fails. is it a known issue?
Am I doing it wrong?
Should I fulfill other prerequisites before compiling AD Stuff?

I'd be happy to get some hints,
thanks in advance!
