ios - Cocoapod "error: could not build module 'UIKit'" -
i'm trying fit mupdf podspec. that's not going want though...
error: not build module 'uikit' this error every time try pod lib lint. in 2 flavours though, depending on exact contents of podspec. before that, context!
tl;dr: brain can't process mupdf , static library dependencies make nice podspec out of it. can help?
file layout
so library mupdf (http://mupdf.com); cloned git repository. comes bunch of .m files, main library written in c , has several dependencies. end few static libraries (.a files). file layout looks this:
mupdf/ # objc files platform/ios/common.{h,m} platform/ios/classes/*.{h,m} # headers , static libraries include/**/*.h platform/ios/thirdparty/*.a the include folder contains headers required libraries in platform/ios/thirdparty. these headers included platform/ios/common.h.
podspec
and podspec looks this:
pod::spec.new |s| # <enter usual podspec yada yada here> s.source_files = "platform/ios/classes/**/*.{h,m}", "platform/ios/common.{h,m}", "include/**/*.h" s.public_header_files = "platform/ios/classes/**/*.h" s.header_mappings_dir = "include" s.libraries = "z" s.vendored_libraries = "platform/ios/thirdparty/*" end based on (and variation of podspec), 2 different errors.
symbol redefinition error
with exact podspec configuration, following errors:
- error | /<path>/mupdf/include/mupdf/fitz/math.h:97:8: error: redefinition of 'fz_point_s' - note | /<path>/mupdf/include/mupdf/fitz/math.h:97:8: note: previous definition here - error | /<path>/mupdf/include/mupdf/fitz/math.h:121:8: error: redefinition of 'fz_rect_s' - note | /<path>/mupdf/include/mupdf/fitz/math.h:121:8: note: previous definition here # etc. etc. - note | target support files/pods-mupdf/pods-mupdf-prefix.pch:2:9: fatal error: not build module 'uikit' circular dependency error
if comment out s.public_header_files line, end circular dependency error. weird!
- note | /privatetarget support files/pods-mupdf/pods-mupdf-umbrella.h:1:9: fatal error: cyclic dependency in module 'uikit': uikit -> foundation -> corefoundation -> mupdf -> uikit conclusion
my brain hurts, please help!
i not sure going on podspec, sorry. how resolved math.h header file conflict - annoyingly tricky right in pod spec.
i have created cocoapod mupdf, , created example application based on pod, , seems work fine.
for reference here pod spec (note out of date; please refer published mupdf pod spec 1 compatible latest version of mupdf , latest cocoapods):
