Description of issue

I have upgraded by Mac to Tahoe. Before that one everything worked. I had gfortran installed (this is the only brew I need, all the rest was installed with MacPorts). However, brew cannot symlink to various root directories, e.g.

I also tried to install gnu plot, the same problems, it finds all stuff it needs, installs gnu plot (I can execute gnuplot), but gnu plot cannot plot anything because Qt is not installed,. I run

brew install Qt

the same problem, cannot symlink to various root directions.

[botantony]

can you run brew link wget --debug?

I successfully installed gnuplot by going meticulously through the output of brew and managing the links, e.g.,

brew link --overwrite libmpc --dry-run

and this solved the problem with gnuplot, it runs now. I had to apply this many times.

However, I still cannot install properly gfortran: the installer went through OK. However, when I run gfortran, only compilation works, there are problems at the linking stage:

MAIN_ in main.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [APPLIC] Error 1

I have tried to search for this undefined symbol, no luck. BTW, the code works on other platforms and I compiled it million times on the previous mac OS. No changes have been made to the code.

Any advice you can give me?

Many thanks
Lev

Not sure about the debug symbols, but you do clearly have wget (and many other formulae with linking problems) installed (see brew doctor output). The only problem is that when you try to upgrade from 1.16.3 to 1.25.0, it fails to symlink (and brew link does not help either). What about brew reinstall wget?
