Different library paths for different build environments - windows

I'm developing a UMDF-driver. The driver needs a different (build of a) library for 32 bit and 64 bit builds.
The TARGETLIBS property in my sources file looks like
TARGETLIBS=\
$(SDK_LIB_PATH)\strsafe.lib \
$(SDK_LIB_PATH)\kernel32.lib \
$(SDK_LIB_PATH)\ole32.lib \
$(SDK_LIB_PATH)\oleaut32.lib \
$(SDK_LIB_PATH)\uuid.lib \
...
..\otherlib\amd64\foo.lib \
but for a x86 build the path for foo.lib must be ..\otherlib\i386\foo.lib.
Obviously there is some mechanism for this in the ddk build system, since $(SDK_LIB_PATH) also points to different locations depending on the build architecture. But I'm unable to find documentation on this subject.
How do I set different library paths in one source file for different build types?

http://technet.microsoft.com/en-us/query/ff552910
Because of this convention, TARGETLIBS entries should specify library names in the following form:
<targetpath>\*\<library_name>
where targetpath is identical to the value assigned to TARGETPATH in the Sources file, and library_name is the full file name of the library to be linked to the executable file. The Build utility replaces the asterisk ( * ) with the target platform type.
That's definitely ok for my current problem. But if someone can offer more general solution i'm all ears...

Passing extra compilation flags to debug build in bitbake recipe

As Bitbake builds -dev and -debug for recipes is it possible for defining compilation definitions specific to debug build for a particular recipe. Lets say I have some source code under DEBUG_INFO for some recipe i.e.,
#ifdef DEBUG_INFO
........... do something
#endif /* DEBUG_INFO */
and uses cmake in bitbake environment.
I want this flag be enabled for the debug binaries generated in the .debug folder. Is this possible?
If I use EXTRA_OECMAKE = "-DDEBUG_INFO" it gets enabled to both dev and debug builds.
No, it is not possible. All packages of a recipe are built in one go, they're just the same files but split somehow.
The only difference is with "special flavors" of a recipe (native, nativesdk, target, multilib, toolchain-specific recipes, etc...), in that case, you can have different flags but still, all the packages resulting from the build of this "flavor" will be built with the same flag.
If you want to build another variant of a package where a certain CMake flag is set in the compilation, you can create a variant of the recipe. If the main recipe is named my-app_git.bb you can create another recipe file named my-app-tweak_git.bb and a common base, my-app.inc. In the bb files, include the inc file:
require my-app.inc
Move most of what's now in my-app_git.bb to my_app.inc, e.g. SRC_URI, but define different contents for EXTRA_OECMAKE in the .bb files.
Now you will have to decide which one of my-app and my-app-tweak goes into the image by specifying either my-app or my-app-tweak in an IMAGE_INSTALL definition.
This is not exactly what you asked for, but as has been stated by qschulz, you cannot change the contents of the -dev and -dbg sub-packages.
Also note that dbg and dev can be considered reserved words for variants of the package name, so if you want to use something other than tweak, as in my example, you cannot use any of them.

rosrun does not work after sourcing my own catkin workspace

I'm following the ROS-tutorial and I am facing the following behavior after creating my own package:
If try to execute any installed package (e.g. any_package), I get the following error:
[rosrun] Couldn't find executable named <any_package> below /opt/ros/kinetic/share/<any_package>
[rosrun] Found the following, but they're either not files
[rosrun] or not executable:
[rosrun] /opt/ros/kinetic/share/<any_package>
Any help?
EDIT:
If I execute catkin_find --without-underlays --libexec --share <any_package>, it gives me the following output:
Multiple packages found with the same name "my_package":
- my_new_package/my_package
- my_new_package/my_package_2
I assume that you have a tainted workspace.
I assume that you've just copied the my_package to my_package_2 without editing the package.xml file in my_package_2.
It is not really mentioned in the tutorial, since it assumes that you use the proper commands which creates a manifest file with a unique package name.
Just edit the name-tag as follows:
<name>my_package</name>
to
<name>my_package_2</name>
in the corresponding folder.
You have to make sure you edit CmakeLists.txt according to your compile version, c++ executable declaration & Specify libraries to link a library
Below are step step modification and then run catkin_make before running your project:
step 1
add_compile_options(-std=c++11)
step 2
## Declare a C++ executable
## With catkin_make all packages are built within a single CMake context
## The recommended prefix ensures that target names across packages don't collide
add_executable(${PROJECT_NAME}_node src/myproject_node.cpp)
step 3
## Specify libraries to link a library or executable target against
target_link_libraries(${PROJECT_NAME}_node
${catkin_LIBRARIES}
)

Bazel environment variables in build rules

I want to refer to a DirectX SDK in the BUILD file. The problem is that (as far as I understand) Bazel supports passing environment variables only through --action_env=DXSDK_DIR argument for Bazel and it is meant to be used in actions, which must be defined in a plugin (.bzl file).
Is there any easier way to refer to the environment variable by using it as Make variable (includes = [ "$(DXSDK_DIR)/Include" ]) or do I need to write a plugin?
In principle you need a cc_library rule whose hdrs attribute globs the DirectX headers. For that you need to pretend that the DX SDK is part of your source tree. Bazel offers "repository rules" for that purpose.
1. Create a repository rule for the DirectX SDK
Depending on whether the SDK's location is known or needs to be discovered, you have two options.
a. Fixed SDK location
You can use this approach if you don't need to read any environment variables, run any binaries, or query the registry to find where the SDK is. This is the case if everyone who builds your rules will install the SDK to the same location.
Just add a new_local_repository rule to your WORKSPACE file, point the rule's path at the SDK's directory and write a simple build_file_content for it.
Example:
new_local_repository(
name = "directx_sdk",
path = "c:/program files/directx/sdk/includes",
build_file_contents = """
cc_library(
name = "sdk",
hdrs = glob(["**/*.h"]),
visibility = ["//visibility:public"],
)
""")
This rule creates the #directx_sdk repository with one rule in its root package, #directx_sdk//:sdk.
b. SDK discovery
You need to follow this approach if you need to read environment variables, run binaries, or query the registry to find where the SDK is.
Instead of using a new_local_repository rule, you need to implement your own. More info and examples are here.
Key points:
if your repository rule needs to read environment variables, add them to the list repository_rule(environ), e.g. repository_rule(..., environ = ["DXSDK_DIR"])
if you need to run some binaries that tell you where the SDK is, use repository_ctx.execute. You can use repository_ctx.which to find binaries on the PATH.
if you need to do registry queries, use repository_ctx.execute with reg.exe /query <args>
2. Depend on the SDK's cc_library
In your project, just depend on the SDK's library as if it was an ordinary cc_library:
cc_library(
name = "render",
...
deps = [
...
"#directx_sdk//:sdk",
],
)

CMake error: "INSTALL TARGETS - target Xxx has RESOURCE files but no RESOURCE DESTINATION." when building a bundle on OS X

We are building an application on OS X, the build management being implemented in CMake.
In the CMakeLists.txt of the application, the target is added as:
add_executable(${PROJECT_NAME} MACOSX_BUNDLE
${${PROJECT_NAME}_HEADERS}
${${PROJECT_NAME}_SOURCES}
${${PROJECT_NAME}_RESOURCES}
main.mm
)
With ${PROJECT_NAME}_RESOURCES variable listing the xib and image files. We also set the target properties and configure the installation as follows:
set_target_properties(${PROJECT_NAME} PROPERTIES
VERSION "${VERSION}"
SOVERSION "${SOVERSION}"
RESOURCE "${${PROJECT_NAME}_RESOURCES}"
)
install(TARGETS ${PROJECT_NAME}
BUNDLE DESTINATION ${RUNTIME_OUTPUT_DIRECTORY}
)
Quoting the documentation (emphasis mine):
The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
subsequent properties to be applied to installing a FRAMEWORK shared
library target’s associated files on non-Apple platforms. Rules
defined by these arguments are ignored on Apple platforms because the
associated files are installed into the appropriate locations inside
the framework folder.
So we would understand that specifing a RESOURCE argument to install() would be ignored in our situation. Yet CMake issues this message (in red):
INSTALL TARGETS - target Xxx has RESOURCE files but no RESOURCE
DESTINATION.
EDIT: Setting a value for RESOURCE DESTINATION in the install() command disables the message. In this case, the resources are still copied in the right place into the application bundle, but they are also copied into the provided value.
Is there at least a way to turn off this message without introducing copies that are useless on OS X ?

Can CMake build subprojects (with benefits)?

I have some huge project that is being compiled in CMake.
It is developed for quite a long time, have 8000+ source/header files (over 500Mbytes, over 500 CMakefile.txt files).
They use directory structure like this
PROJECT_NAME
src
/ subdir_name
/ other_dir_name
/ some_different_dir
/ MY_SPECIFIC_DIR <---
/ yet_another_dir
build
and build it out-source, like this:
name#host:~/PROJECT_NAME/build> cmake ../src
name#host:~/PROJECT_NAME/build> make all
then it's build as one BIG binary (details are not important).
I cannot touch anything else, just content of MY_SPECIFIC_DIR - it's source and CMake files.
So, I have source code in MY_SPECIFIC_DIR tweak CMakefile.txt files somehow and would like to build it like this:
name#host:~/PROJECT_NAME/build_specific> cmake ../src/MY_SPECIFIC_DIR
name#host:~/PROJECT_NAME/build_specific> make all
This should build things in MY_SPECIFIC_DIR into single binary with some few links to other subprojects. But also (obviously) don't change anything about how whole project is compiled.
My question is:
Is my desired setup
posible
using CMake?
Can I somehow test in CMakeFile.txt that it is root project and build it in different way then when it is builded as a whole?
Unless, I have to resort to different means and use standard make for this.
I don't know CMake so I'm hoping for YES/NO anwer, preferable even for technique how to achieve this. And then learn the CMake and do it.
Also, I must use CMake version 2.6.
Thanks
Basic concept is to use
if (CMAKE_SOURCE_DIR STREQUAL CMAKE_CURRENT_SOURCE_DIR)
... code for stand-alone app
else()
... what was in this file before
endif()
