tg2sip on FreeBSD

[ogogon]

Can tg2cip, without major modifications, be compiled on the FreeBSD platform?

[Infactum]

Tg2sip itself don't use any platform specific code if I remember correctly.
Anyway I can't say wether it or its dependencies are tested on freeBSD.

1. I've never worked with spdlog, but something is wrong with it. Cmake doesn't want to work with her.
2. What is Td?

Am I doing something wrong?

You are trying to compile against newer version of spdlog (1.8.0) than requested one (0.17).
Td is telegram database library. Btw it has build instructions for freeBSD here.
Most probably you'll need to build all dependencies by yourself. See buildenv and CI scripts as examples and do same this with freeBSD specific.

[ogogon]

You are trying to compile against newer version of spdlog (1.8.0) than requested one (0.17).

As far as I understand, version 0.17 is no longer supported. Where can I get it?
Standard methods for installing programs in FreeBSD offer only version 1.8.0.
Thus, I must not act very correctly. Remove the correctly installed version 1.8.0, and then compile and install the obsolete version without using the software packages control mechanism.

Sorry if my question is tactless, but you have no plans to rewrite your product using the current version spdlog?

[Infactum]

It doesn't matter what version is used by freeBSD package manager.
Build dependencies but don't install them system-wide. Later they will be statically linked to tg2sip binary so your system won't be affected in any way.

I have no plans to update any dependencies to newer versions until current one are working stable and no new features are needed.

[ogogon]

For the Td library, you have set version 1.6.0
find_package(Td 1.6.0 REQUIRED)
Now, the current version is 1.6.8.

They will be compatible, or only need to use 1.6.0?

[Infactum]

If Td uses semver, then 1.6.0 and 1.6.8 should have same API.

Please comment on the following situation.
When compiling, I get diagnostics:

If I make corrections suggested by the compiler, then everything goes without errors.
Here is my version of the CLang and SIP-stack:

ogogon@ogogon:/usr/local/src/tg2sip/build# clang --version
FreeBSD clang version 10.0.0 (git@github.com:llvm/llvm-project.git llvmorg-10.0.0-0-gd32170dbd5b)

Thread model: posix
InstalledDir: /usr/bin
ogogon@ogogon:/usr/local/src/tg2sip/build# pkg info pjsip
pjsip-2.10_1

What does this mean?
There was a bug in the program, but everyone was compiling it? Or have I mistakenly followed the compiler's recommendation and introduced an error into the code?

[Infactum]

Well I'm gonna say it once again: please check existing CI build scripts. Current tg2sip version is build against pjproject 2.9. Your package version is 2.10. There is even issue about this here.
Also pjproject must be properly configured before compilation with config_site.h. Thats the second reason why you should build it yourself.
