I don't think there's anyone really maintaining this at the moment, so it's really nice to see an update! When you're ready please setup a PR and I or someone else can look at merging code in.
Thanks for your reply, Stephen.
I'd be happy to contribute a PR at some point. In fact, on the macOS side, I'm pretty much almost done with my changes. It's just the windows build is a bit of pain since I haven't developed on Windows for quite a while.
Anyway, let's see how it goes.
With regard to maintenance and general plans for Max, I have plans (after defending) to update my port of the Lazzarini csound object for PD, which is over at: https://github.com/iainctduncan/csound_max. It is a much more minimal version that uses the Csound API only.
I would like to get that working on Apple Silicon, and perhaps also port the midi functionality that is not in there yet from Victor's version. But this one is much more complicated!
Funnily enough, I also have an ancillary repo for testing common build improvements to both csound externals.
I'd love to chat about teaming up to improve the csound_max external after I'm done my defense (July 24th)! Feel free to email me off github.
@kunstmusik I'm struggling with linking csound with csound_tilde on windows, as I'm using MSVC for the time being but the errors are mostly to do with runtime library linking issues vis-a-vis libcsound.
On csound's CMakeList.txt
, I found the option of MinGW compilation, and also some useful info about MSVC compilation configuration:
if(WIN32 AND NOT MSVC)
if(EXISTS "C:/MinGW/include")
include_directories(C:/MinGW/include)
else()
MESSAGE(STATUS "MinGW include dir not found.")
endif()
set(CMAKE_MODULE_LINKER_FLAGS "${CMAKE_MODULE_LINKER_FLAGS} -Wl,--add-stdcall-alias")
endif()
if(WIN32)
set(CMAKE_SHARED_LIBRARY_PREFIX "")
set(CMAKE_SHARED_MODULE_PREFIX "")
set(CSOUND_WINDOWS_LIBRARIES
advapi32
comctl32
comdlg32
glu32
kernel32
odbc32
odbccp32
ole32
oleaut32
shell32
user32
uuid
winmm
winspool
ws2_32
wsock32)
if(MSVC)
# Experimented with flags but did not make change performance results
#set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} /Oi /fp:fast /arch:AVX2")
#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /Oi /fp:fast /arch:AVX2")
# Replace the default CRT linkage from dynamic (MD) to static (MT)
if(STATIC_CRT STREQUAL "ON")
foreach(flag_var
CMAKE_C_FLAGS CMAKE_C_FLAGS_RELEASE CMAKE_C_FLAGS_DEBUG
CMAKE_CXX_FLAGS CMAKE_CXX_FLAGS_DEBUG CMAKE_CXX_FLAGS_RELEASE
CMAKE_CXX_FLAGS_MINSIZEREL CMAKE_CXX_FLAGS_RELWITHDEBINFO)
string(REPLACE "/MD" "-MT" ${flag_var} "${${flag_var}}")
endforeach()
message(STATUS "Using static CRT linkage /MT")
endif()
else()
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -mstackrealign -static-libgcc -static")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mstackrealign -static-libstdc++ -static-libgcc -static")
set_target_properties(${CSOUNDLIB} PROPERTIES LINK_FLAGS "-static-libstdc++ -static-libgcc -static")
set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -static-libstdc++ -static-libgcc -static")
endif()
endif()
It would be useful to know which compiler is used for the default csound binary builds that are currently available for download on csound's website in case I am trying to link csound_tilde
compiled using MSVC to a libcsound
compiled with MinGW (see stackoverflow case)
No worries, I found the answer in the csound docs in csound/platform/README.md
:
Visual Studio via CMake is the supported build platform for Windows with Csound. MSYS or Cygwin may no longer work and are not actively maintained. System dependencies for Windows can be installed with Chocolately or Scoop. VCPKG is used as the 3rd party library dependency manager.
Hi,
As I wanted to include the
csound~
external in a standalone, I've been spending some time on a recent fork with the initial objective of getting it to work for me on macOS and also to create a relocatable external (not dependent on local~/Library/Frameworks/Csound64.framework
To that end, I've made some progress and I think some of it would be worth contributing back to the project in a PR at some point if I get past some frustrating windows compilation issues (windows is not my platform of choice -- I'd appreciate some advice if possible).
In any case, here's a brief list of the changes so:
Converted to Max Package with regular cross-platform structure
Added max-sdk-base as git submodule
Added Makefile frontend for simplified macOS builds
Fixed macOS compilation errors related to deprecated apis (dropped carbon and rewrote Launch code) and also made a few general code improvements (complete diff here):
Removed all
using namespace std
statements and converted unqualified terms to qualified, and renamedbyte
indefinitions.h
tocsbyte
because there were name collisions between std::byte (added in c++ 17) and former.Dropped use of
auto_ptr
in csound~.cpp, which was removed in c++17, : converted to std::unique_ptr.Dropped some deprecated or obsolete api usage, for example
FSRef
->CFURLRef
Added Build variants with associated scripts:
macOS - local build: non-relocatable, dynamically linked to local csound library or framework
macOS - hybrid build: relocatable with static csound + dynamic dependencies
macOS - release build: relocatable 100% static build using vcpkg.
windows - NOT complete due to residual linking errors but with updated cmake build...
