Re: Legacy Support for GHC-Based Projects
A stack binary is required to build stack, and to the best of my knowledge there is no ppc stack binary: https://github.com/commercialhaskell/stack/search?q=ppc=. I recommend such requests be taken upstream, as there is no “fix” for PPC on our end.Back to topic, is anyone able to confirm that stack-based pandoc is working (or not) on a legacy platform also supported by stack back to Sierra?On Jan 17, 2023, at 09:08, Sergio Had wrote:

stack on ppc or other very old non-supported systems will be extraordinarily fragile and time-consuming, and I expect difficult to anticipate sustained MacPorts support, especially as stack migrates to arm.

If anyone is good at cross-compiling, please ping me. We need to first build the latest GHC on 10.6.8 Intel and then cross-compile GHC for PPC.

I used this code to force stack-based builds on macOS versions that predate Apple Silicon. After Apple Silicon, we need cabal-based builds for native binaries.
set arm64_minimum_supported_major_version 20
if {${os.platform} eq {darwin}
&& ${os.major} < ${arm64_minimum_supported_major_version}} {
# use stack to build x86_64 binaries
default_variants-append \
+stack
}
stack-based stack builds work all the way back to Snow Leopard: https://ports.macports.org/port/stack/details/. I’d expect the same of pandoc, but it only builds back to Sierra: https://ports.macports.org/port/pandoc/details/
Is anyone able to suggest profile code that will accomplish this? Is this related to the design choice to use a the port variant +stack to specify the build tool?

If PPC is fixed on our end, I will try to upstream patches, so we won’t need to

Re: Legacy Support for GHC-Based Projects
To clarify, the question is how to specify that these ports use the latest stack version for builds on legacy systems. Does it work for pandoc now?stack on ppc or other very old non-supported systems will be extraordinarily fragile and time-consuming, and I expect difficult to anticipate sustained MacPorts support, especially as stack migrates to arm.On Jan 17, 2023, at 08:39, Sergio Had wrote:
