With CMake i can build libwxPDFView.a library with CodeBlocks(20) and MinW64 compiler
But building C:/wxPDFView-1.0/samples/simple i have problem.
Pdfium libs are at c:\repo\Libraries\pdfium\lib\lib and bin
Thank you.
Jim

I am facing an issue while cross-compiling an awsclient application. My build environment is Ubuntu 20.04 and Buildroot running from Docker Desktop for Windows. I am using cmake tool. But when I do make I am getting below erros:

One thing I noticed while doing cmake before make is cmake generated some warnings about linker.
CMake Warning at src/CMakeLists.txt:17 (add_executable):
Cannot generate a safe linker search path for target awsclient because
files in some directories may conflict with libraries in implicit
directories:
link library [libcurl.so] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
/root/br-tcg4/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/arm-linux- gnueabihf/libc/usr/lib

/root/br-tcg4/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf/arm-linux- gnueabihf/libc/usr/lib
Some of these libraries may not be found correctly.
The dir /root/br-tcg4/opt/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf is the location of the toolchain I am using. I am not sure if these warnings are reason for above issue.

I am not sure why we need to use this file which is genearted from populate_sdk by yocto.
Can someone please let me know how to resolve this?
Thanks in advance.
P.S: I am new to Cmake and please let me know if there are any missing info.
I am using vcpkg for the first time with amqpcpp. I am testing it out with cmake to get a project setup using a library. vcpkg installs the package correctly and cmake has no trouble finding the target amqpcpp. There is some issue with the linker that I cannot solve. Below is my CMakeLists.txt.
cmake_minimum_required(VERSION 3.15)
set(VCPKG_TARGET_TRIPLET x86-windows )
set(CMAKE_TOOLCHAIN_FILE "C:/Users/reine/vcpkg/scripts/buildsystems/vcpkg.cmake" CACHE STRING "")
project(amqp_test)
set(CMAKE_CXX_STANDARD 11)
find_package(amqpcpp CONFIG REQUIRED)
include_directories(${amqpcpp_INCLUDE_DIR})
add_executable(amqp_test main.cpp)
target_link_libraries(${PROJECT_NAME} PRIVATE amqpcpp)
And below is the linker error that I am experiencing. The ConnectionImpl does indeed exist. Why are the file names so crazy? I imagine this is something that is done to prevent double referencing of an object. I am thinking this is where my problem is.
c:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: CMakeFiles\amqp_test.dir/objects.a(main.cpp.obj): in function `ZN4AMQP10ConnectionD1Ev':
C:/Users/reine/vcpkg/installed/x86-windows/include/amqpcpp/connection.h:70: undefined reference to `AMQP::ConnectionImpl::~ConnectionImpl()'
I have done my due diligence searching this type of linker error and am completely stuck.

I built mono 5.20.1.19 from tarball successfully. But the build of master from github was failed. Instead of using a existing mono installation for the build, I run make get-monolite-latest for the mcs. On RedHat 6.9 (gcc6.3, cmake3.7.2) the build was crashed(segment fault). On SUSE 12.4(gcc6.3, cmake 3.5.2), the build ended with errors. I thought I might need to checkout the branch 5.20.1.19, but I couldn't find any branch newer then 4.8. Why there doesn't exist such a branch? Thanks in advance. Below are my build errors:

I'm trying to build a project that includes log4c for the Jetson Nano. log4c is dependent on expat. expat has a CMakeLists.txt file and plays nicely with CMake. I'm having trouble telling log4c where the build output of expat lives to complete the link phase.
I have my main CMakeLists.txt file performing the following:
add_subdirectory(dependencies/libexpat/expat)
add_subdirectory(dependencies/libuuid-1.0.3)
add_subdirectory(dependencies/log4c-1.2.4)
expat builds with no issues. My CMakeLists.txt file for log4c is listed below:
# ------------------------------------------------------- MINIMUM CMAKE VERSION
cmake_minimum_required(VERSION 3.10)
include(ExternalProject)
# ---------------------------------------------------------------- PROJECT NAME
set(THIS log4c)
# ------------------------------------------------------------ EXTERNAL PROJECT
if("${BUILD_PLATFORM}" STREQUAL "nano")
set(HOST "--host=aarch64-linux-gnu")
endif()
file(GLOB_RECURSE SRC_FILES

)
file(TOUCH ${SRC_FILES})
ExternalProject_Add(${THIS}_build

add_library(${THIS} INTERFACE)
target_link_libraries(${THIS} INTERFACE ${CMAKE_INSTALL_PREFIX}/usr/lib/liblog4c.so)
target_include_directories(${THIS} INTERFACE ${CMAKE_INSTALL_PREFIX}/usr/include)
log4c configures and builds correctly, but it fails to link with the following error messages:

How do I tell log4c where expat was built at.
I have these files in the directory:
CMakeLists.txt datalink.c datalink.h protocol.a protocol.h
All these files were got from my teacher except CMakeLists.txt.
#CMakeLists.txt
cmake_minimum_required(VERSION 3.5)
project(DataLinkSimulator)
INCLUDE_DIRECTORIES(.)
set(SOURCE_FILES datalink.c protocol.a datalink.h protocol.h)
add_executable(DataLinkSimulator ${SOURCE_FILES})
target_link_libraries(DataLinkSimulator protocol.a)
I run 'cmake .' in this directory, and it works.
However, when I run 'make' , it gives me these errors.

The error "cannot find -lprotocol" must caused by ld's mistaking protocol as a shared lib. But my protocol is a static lib. So I am confused.
If I edit makefile by myself instead of using cmake, it works correctly.

In order to understand the error you need to launch make command from the command line using verbose mode; on Linux paltform it means launching:
make VERBOSE=1
In this manner you will have the entire command line used to compile the code.
In order to resolve your error you could:
add a link_directories(directory_where_you_have_library) CMake line adding the directory where you have protocol.a before target_link_libraries line
add protocol.a with absolute path.
Your modified Makefile works because probably you have it in the same directory of all the files while CMake creates many Makefiles in various directories starting from build root directory so it needs -L gcc flags (obtainable through link_directories) or -l with absolute path (obtainable adding protocol.a with absolute path).
