Help building Sage 9.3

[Hongli Zhao]

Hi,

I'm following this page: https://doc.sagemath.org/html/en/developer/walk_through.html

to pull the source code. However I'm having a lot of trouble compiling the code. I did ```conda deactivate``` and first ran ```./configure```, then repeatedly I see these errors regardless if I ```brew install``` these packages (I already have these packages but the errors are still showing):

Could someone help? Thanks a lot

These are not errors, but the fact that "readline" is included there suggests that you did not run the "source" command shown there.

Thanks professor, I had to delete and re-download the source code repeatedly because ```./sage``` kept crashing for some reason,

I ran ```make``` and now I found these errors...

Attached is the cypari log file, sorry.

in your log one sees

  gcc -bundle -undefined dynamic_lookup -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -L/Users/honglizhao/Desktop/sage_research/code/sage/local/lib -Wl,-rpath,/Users/honglizhao/Desktop/sage_research/code/sage/local/lib -O2 -g -march=native build/temp.macosx-11-x86_64-3.9/cypari2/closure.o -L/Users/honglizhao/Desktop/sage_research/code/sage/local/lib -L/Users/honglizhao/Desktop/sage_research/code/sage/local/lib64 -lgmp -lpari -o build/lib.macosx-11-x86_64-3.9/cypari2/closure.cpython-39-darwin.so -lpari
  ld: library not found for -lgmp

Usually this points out at some kind of misconfiguration. Did you forget to run

source .homebrew_build_env

before this round of make?
