Describe the bug

[⠔] Compiling... [⠔] Compiling 1 files with Solc 0.8.26 [⠑] Solc 0.8.26 finished in 490.40s

I don't know why，macos sonoma 14.6.1

Is it a problem with my operating system or a network problem? Is the compilation local or depends on the network?

Hey @vseae thanks for the report

If possible, could you provide a link to the source code that you are building? A single file should not take that long. When re-running the build step after forge clean are you experiencing the same or similar build time?

My computer is m3 24gb system version Sonoma 14.6.1

The test script tests a token, inherits the Test contract of forge, and the configuration is enabled via_ir = true, compiler version 0.8.26

When I enable via_ir, it takes me at least a minute to compile a file.

This problem seems to only occur in the inheritance of the forge test contract and the latest macos system.

Compiling contract files is several times slower than hardhat.

When I enable via_ir, it takes me at least a minute to compile a file.

this is via_ir overhead

all of this is solc time
