Title: Unable to compile ezremaster due errors
Post by: mcgiwer on August 29, 2022, 12:15:04 PM

Hello. I wanted to let know about that when I attempted to compile from the sources the ezremaster, I had recieved following g++ errors:

Code: [Select]

ezremaster.cxx:29:22: error: ‘unlink’ was not declared in this scope

Please fix it asap. Thanks

Did you use this?

yes, but I had put some modifications to the script:

Code: [Select]

#!/bin/sh

build_dir=$(dirname $0)

fluid -c ${build_dir}/ezremaster.fl
g++ -O3 -Os -fno-exceptions -Wno-unused-result -fpic -o ${build_dir}/ezremaster ${build_dir}/ezremaster.cxx

if [ -f ${build_dir}/ezremaster ]; then strip ${build_dir}/ezremaster; chmod -vf 755 ${build_dir}/ezremaster; fi
if [ -f ${build_dir}/remaster.sh ]; then chmod -vf 755 ${build_dir}/remaster.sh; fi

if [ ! -d ${build_dir}/share/applications ]; then mkdir -pvm 777 ${build_dir}/share/applications; fi
if [ ! -d ${build_dir}/share/pixmaps ]; then mkdir -pvm 777 ${build_dir}/share/pixmaps; fi

Fix for the

Code: [Select]

ezremaster.cxx:29:22: error: ‘unlink’ was not declared in this scope  unlink("scm.lst"); error:

In the file ezlink.fl replace following line:

Code: [Select]

unlink("scm.lst");
with:

Code: [Select]

system ("unlink scm.lst");

Update:
After fixing the "unlink" error, I had got a new set of errors, with seem to be broken references to the generated interface items:

Those are because you removed -lfltk from the script.
