Thanks, that appears to fix the problem.

 

Before changing ADSupport/supportApp/GraphicsMagickSrc/lcms/src/Makefile:

 

[epics@millenia src]$ make -sj clean

[epics@millenia src]$ make -sj

Malformed UTF-8 character (fatal) at /corvette/usr/local/epics-devel/base-7.0.1/bin/linux-x86_64/mkmf.pl line 136, <FILE> line 5573.

Malformed UTF-8 character (fatal) at /corvette/usr/local/epics-devel/base-7.0.1/bin/linux-x86_64/mkmf.pl line 136, <FILE> line 5573.

../cmscgats.c: In function ‘ReadReal’:

../cmscgats.c:577:9: warning: this ‘else’ clause does not guard... [-Wmisleading-indentation]

         else

 

After changing the Makefile to redefine PERL:

 

[epics@millenia src]$ make -sj clean

[epics@millenia src]$ make -sj

../cmscgats.c: In function ‘ReadReal’:

../cmscgats.c:577:9: warning: this ‘else’ clause does not guard... [-Wmisleading-indentation]

         else
