Ran into another issue with tdegraphics that I can't solve by a dependency review:

Is this a CMake issue? Linker error? What to look for?
Do you have SANE installed?
Check your build log for the following:
-- checking for 'libkscan' -- ok, activated for build
Check your CMakeCache.txt for this:
//Build libkscan BUILD_LIBKSCAN:BOOL=ON
Darrell
Hmm... yes on both accounts:
-- checking for 'libkscan' -- ok, activated for build
[19:35 providence:/home/david/bld/david/build/src/build] # grep -i libkscan CMakeCache.txt //Build libkscan BUILD_LIBKSCAN:BOOL=ON libksane_BINARY_DIR:STATIC=/build/src/build/libkscan libksane_SOURCE_DIR:STATIC=/build/src/tdegraphics/libkscan
Is this a new gcc issue? I have gcc 4.6.2-7... How would I check?
I cannot read cmake very well, but it looks like it gets to about line 584 in libkscan/CMakeFiles/kscan-shared.dir/build.make:
@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --red --bold"Linking CXX shared library libkscan.so" cd /build/src/build/libkscan && $(CMAKE_COMMAND) -E cmake_link_script CMakeFiles/kscan-shared.dir/link.txt --verbose=$(VERBOSE) cd /build/src/build/libkscan && $(CMAKE_COMMAND) -E cmake_symlink_library libkscan.so.1.0.0 libkscan.so.1 libkscan.so
libkscan/libkscan.so.1: libkscan/libkscan.so.1.0.0
libkscan/libkscan.so: libkscan/libkscan.so.1.0.0
Because it gets to:
[ 31%] Building CXX object libkscan/CMakeFiles/kscan-shared.dir/imgscaninfo.cpp.o
Then dies. Any ideas?
I think I'm getting closer to at least finding where things are going wrong. Can someone confirm the order that the build system will go though the files in the libkscan/CMakeFiles/kscan-shared.dir? I don't know how the intricacies work, but it looks like it works something like this:
chroot/david/build/src/build/libkscan> ll CMakeFiles/ total 12 drwxr-xr-x 2 nobody nobody 4096 Mar 6 19:35 kscan-shared.dir -rw-r--r-- 1 nobody nobody 970 Mar 6 19:30 CMakeDirectoryInformation.cmake -rw-r--r-- 1 nobody nobody 2 Mar 6 19:30 progress.marks
Path information is set from CMakeDirectoryInformation.cmake

Then it drops into the CMakeFiles/kscan-shared.dir

Where it then reads the 'flags.txt, does make for 'build.make' and then uses 'link.txt' for the linker. In this process, 'flags.txt' looks to have the correct include information:
chroot/david/build/src/build/libkscan> cat CMakeFiles/kscan-shared.dir/flags.make # CMAKE generated file: DO NOT EDIT! # Generated by "Unix Makefiles" Generator, CMake Version 2.8

CXX_DEFINES = -Dkscan_shared_EXPORTS -DHAVE_CONFIG_H
The question is build.make -- is the symlink_library stuff correct? It looks like it, but I don't know. This is where the build craters:
libkscan/libkscan.so.1.0.0: libkscan/CMakeFiles/kscan-shared.dir/link.txt @$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --red --bold "Linking CXX shared library libkscan.so" cd /build/src/build/libkscan && $(CMAKE_COMMAND) -E cmake_link_script CMakeFiles/kscan-shared.dir/link.txt --verbose=$(VERBOSE) cd /build/src/build/libkscan && $(CMAKE_COMMAND) -E cmake_symlink_library libkscan.so.1.0.0 libkscan.so.1 libkscan.so
libkscan/libkscan.so.1: libkscan/libkscan.so.1.0.0
libkscan/libkscan.so: libkscan/libkscan.so.1.0.0
