Conan version nmos-cpp/cci.20240223

[macphersonjamie]

Hi

I’m having problems with the latest nmos version in conan 20240223 – it gives me the following error when I issue the command:-

conan install --tool-requires=nmos-cpp/cci.20240223

ERROR: Missing prebuilt package for 'nmos-cpp/cci.20240223'. You can try:
- List all available packages using 'conan list "nmos-cpp/cci.20240223:*" -r=remote'
- Explain missing binaries: replace 'conan install ...' with 'conan graph explain ...'
- Try to build locally from sources using the '--build=nmos-cpp/cci.20240223' argument

The previous version cci.20221203 – works fine for me with the above install command.

I have the following settings

[settings]
arch=x86_64
build_type=Release
compiler=gcc
compiler.cppstd=gnu17
compiler.libcxx=libstdc++11
compiler.version=11
os=Linux

Is it missing a package ?

Many thanks

Jamie

My profile is same as yours:

[settings]
arch=x86_64
build_type=Release
compiler=gcc
compiler.cppstd=gnu17
compiler.libcxx=libstdc++11
compiler.version=11
os=Linux

I checked my local conan cache on Linux environment and it was working fine. However after clearing the cache, I get the same result. Doing as the message recommends and using conan graph explain ..., it says:

Something to investigate... not sure what the impact of the indicate diff is.

Doing the other thing the message recommended and adding --build=nmos-cpp/cci.20240223 to the command seemed to solve the problem (by building locally, which I agree shouldn't be necessary for a common profile like this!).

I'm a heavy conan user and can tell you, I basically always run conan whatever ... --build=missing cause there is too many conflicts. In you case the funny thingh is, you have gnu17 as the cppstd. Which I think is the default that conan profile detect will create. While it looks like the CCI-CI builds the non-gnu ones ;)
