A number of things don't make sense here.
Firstly, to confirm, if I take the current (4.5) build_all.bat file, set API_BUILD_CCS_CES=ON and use the batch file as is, then I duly get all the CCS/CES files produced below C:\Apache24\bin\iconv. I presume you're using the current "CMakeLists - apr-iconv-1.2.2.txt" file downloaded from https://pastebin.com/axU1miF0.
Secondly, from the snippet of log you've posted, it's not clear why your build is not creating static apriconv-1.lib and shared libapriconv-1.lib, since these should be built by CMake BEFORE conditionally trying to build any CCS/CES files.
Your log starts at 0% with: | Code: | [ 0%] Building C object CMakeFiles/cp285.dir/ccs/cp285.c.obj
cp285.c |
whereas mine builds the apriconv libraries first (up to 3%), and then starts on the first CCS file adobe-stdenc.c
| Code: | ...
[ 3%] Building C object CMakeFiles/libapriconv.dir/lib/iconv_uc.c.obj
iconv_uc.c
[ 3%] Linking C shared library libapriconv-1.dll
[ 3%] Built target libapriconv
[ 3%] Building C object CMakeFiles/adobe-stdenc.dir/ccs/adobe-stdenc.c.obj
adobe-stdenc.c
[ 3%] Linking C shared library adobe-stdenc.so
[ 3%] Built target adobe-stdenc |
Thirdly, why is your first CCS file cp285.c, when the first source file in the CCS folder is abobe-stdenc.c? I count 196 C source files in that folder.
I also note you are placing your CMake build files below
-- Build files have been written to: C:/httpd/srclib/apr-iconv-1.2.2 whereas mine get placed here (package name with no version number details)
-- Build files have been written to: C:/Development/apache24/build/apr-iconv This rather suggests you've changed the BUILD_BASE and/or script logic, in which case I can't really advise further.
I like keeping the build files away from the source tree, but from what you've posted I can't decide if that's what you've done. |

Yes, I used the "CMakeLists - apr-iconv-1.2.2.txt" file downloaded from there.

It's true that there are some path differences; I moved all dependencies to Apache's "srclib" directory for Linux compatibility, but basically, apart from the paths, there are no differences in the command-line compilation.
This is the output when API_BUILD_CCS_CES=ON:
| Code: | ...
C:\httpd\srclib\apr-1.7.6>cd C:\httpd\srclib\apr-iconv-1.2.2
C:\httpd\srclib\apr-iconv-1.2.2>CMAKE -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=/phpStudy/Apache -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/phpStudy/Apache/lib -DAPI_BUILD_CCS_CES=OFF -DINSTALL_PDB=OFF

And this is the output when API_BUILD_CCS_CES=OFF (I deleted the apr-iconv folder that had previously failed to compile and then re-extracted the apr-iconv folder before compiling):

The version of cmake I'm using is installed directly through the C++ CMake tools for Windows individual component of the Visual Studio Installer:
| Code: | C:\httpd\srclib\apr-iconv-1.2.2>cmake --version
cmake version 3.20.21032501-MSVC_2
CMake suite maintained and supported by Kitware (kitware.com/cmake). |
The compilation command line is different except for the value of API_BUILD_CCS_CES; ON will cause an error, OFF will not. |

I've been looking at your follow-up post details, and run your build commands locally, and can't reproduce the effect your seeing.
As mentioned before, for me things build as expected on both VS2026 and VS2022, but suffice to say your final comment reveals your running an older version of CMake; the one that comes with Visual Studio 2019, and I suspect that's the issue here.
| Code: | C:\httpd\srclib\apr-iconv-1.2.2>cmake --version
cmake version 3.20.21032501-MSVC_2 |
My VS18 CMake is currently at V3.29.2, and VS17 CMake at V3.31.6
Looking at file "CMakeLists - apr-iconv-1.2.2.txt", the code to add the APR-ICONV libraries comes before the conditional block to build the CCS/CES files; yet with your CMake it appears to try and build the CCS/CES files first.
| Code: | IF(API_BUILD_CCS_CES)
# Define additional libraries for linking CCS/CES modules
#
SET(API_LIBRARIES ${CMAKE_BINARY_DIR}/libapriconv-1.lib)
# Define list of CCS source files.
#
FILE(GLOB APICONV_CCS_SOURCES ccs/*.c)
FOREACH(CCS_NAME ${APICONV_CCS_SOURCES})
# Define module name
#
STRING(REGEX REPLACE ".*/([^\\+]+).c" "\\1" MOD_NAME ${CCS_NAME})
ADD_LIBRARY(${MOD_NAME} SHARED ${CCS_NAME})
SET(INSTALL_CCS ${INSTALL_CCS} ${CMAKE_BINARY_DIR}/${MOD_NAME}.so)
TARGET_LINK_LIBRARIES(${MOD_NAME} ${APR_LIBRARIES} ${API_LIBRARIES} ${EXTRA_LIBRARIES})
SET_TARGET_PROPERTIES(${MOD_NAME} PROPERTIES OUTPUT_NAME ${MOD_NAME})
SET_TARGET_PROPERTIES(${MOD_NAME} PROPERTIES SUFFIX .so)
SET_TARGET_PROPERTIES(${MOD_NAME} PROPERTIES COMPILE_FLAGS "-DNDEBUG -DWIN32 -D_WINDOWS")
ENDFOREACH()
|
Note the TARGET_LINK_LIBRARIES() dependency includes ${API_LIBRARIES}, which should be built beforehand.
However, CMake schedules targets and their build order based on a dependency tree it deduces at configure time, and I suspect the later versions of CMake include improvements in how they resolve target link dependencies.
I don't have access to this older version of CMake, so could I suggest you change the following lines in your CMakeLists.txt file (two of them), and let me know if that solves the problem.
Change
TARGET_LINK_LIBRARIES(${MOD_NAME} ${APR_LIBRARIES} ${API_LIBRARIES} ${EXTRA_LIBRARIES})
to
TARGET_LINK_LIBRARIES(${MOD_NAME} libapriconv ${APR_LIBRARIES} ${EXTRA_LIBRARIES}) If that works, I'll update the Pastebin "CMakeLists - apr-iconv-1.2.2.txt" file accordingly.
Re your CCS/CES files starting with cp285.c rather than abobe-stdenc.c; could there be some difference in the older version of the CMake FILE(GLOB) command that builds the list of CCS/CES files to compile, whereby the returned list isn't pre-sorted? Just a guess. |

That's exactly the problem here, I fixed it as you said:
| Code: | ...
FOREACH(CCS_NAME ${APICONV_CCS_SOURCES})
...
TARGET_LINK_LIBRARIES(${MOD_NAME} libapriconv ${APR_LIBRARIES} ${EXTRA_LIBRARIES})
...
ENDFOREACH()
...
FOREACH(CES_NAME ${APICONV_CES_SOURCES})
...
TARGET_LINK_LIBRARIES(${MOD_NAME} libapriconv ${APR_LIBRARIES} ${EXTRA_LIBRARIES})
...
ENDFOREACH() |
It fixed the error and built apr-iconv + CCS/CES.
Here's a comparison of the differences between the two CMakeLists.txt files (before and after modification): https://www.diffchecker.com/Uo37EO3e/ |

Glad that fixed your problem.
Pastebin "CMakeLists - apr-iconv-1.2.2.txt" file updated. |
