 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2
 Keywords:              |       Port:  gdcm, charls
------------------------+---------------------------------
 [https://build.macports.org/builders/ports-10.8_x86_64-builder/builds/17987/steps
 /install-port/logs/stdio gdcm does not build] with charls 2.1.0:

 {{{
 /opt/local/var/macports/build/_opt_bblocal_var_buildworker_ports_build_ports_science_gdcm/gdcm/work/gdcm-3.0.5/Utilities/gdcm_charls.h:21:11:
 fatal error: 'CharLS/charls.h' file not found
 # include <CharLS/charls.h>
           ^
 }}}

 This makes sense since the buildbot workers use a case-sensitive
 filesystem and the file provided by charls 2.1.0 is charls/charls.h not
 CharLS/charls.h.

 gdcm used to build successfully with charls 2.0.0 e.g.
 [https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/82607/steps
 /install-port/logs/stdio this log from 10.13]. There the configure output
 says:

 {{{
 -- Found CHARLS: /opt/local/lib/libCharLS.dylib
 }}}

 What appears to have happened is that charls changed the capitalization of
 its include directory and library between 2.0.0 and 2.1.0. In 2.0.0, it's
 CharLS; in 2.1.0, it's charls.

 Was this change in capitalization intentional? I don't see it mentioned in
 the charls 2.1.0 release notes. Nothing changed in the portfile between
 2.0.0 and 2.1.0 to account for this. Veence, can you figure this out,
 maybe ask the developers of charls and determine which capitalization they
 intend to use from now on? Then we can make sure the charls port uses that
 capitalization in its include dir and library name. Then we can revbump
 and modify all ports that use charls to use that capitalization.
