Failed to build gcc8: command execution failed

[manulcaux]

Hi,

I just installed the new Xcode 13.4 and the associated command-line tools and wanted to update my port installation.

After a successful port selfupdate, I ran sudo port upgrade outdated to upgrade all my packages and got this error :

I tried uninstalling gcc8, did a port clean gcc8 and ran again the port upgrade outdated command that ended with the same error...

Remember to use WikiFormatting.

While this might be something we could fix, I see that you are on Monterey and are trying to use gcc8, which is old and predates Monterey and may not be suitable for use on Monterey. Do you specifically require this old version of gcc? If not, try the latest released version (gcc11) or the latest development version (gcc-devel).

Hi, many thanks for helping. Indeed, I do not think I need gcc8, but all my attempts to remove it form my port installation didn't work, when I run sudo port upgrade outdated, it still try to install gcc8... Please let me know what should I do to be sure the upgrade outdated command does not try to install it. Cheers,

[ryandesign (Ryan Carsten Schmidt)]

Then something you have installed depends on gcc8. Figure out what it is by running:

port installed depends:gcc8

For each port listed, if you don't need it, try to uninstall it. If you do need it, check if it perhaps offers variants for different gcc versions:

port variants putThePortNameHere

Install the port with a newer gcc variant:

sudo port install putThePortNameHere +gcc11

or perhaps the port is set up to pick the newest gcc variant if you don't pick one; if so, do that:

sudo port install putThePortNameHere

Another way to identify what is using gcc8:

sudo port uninstall gcc8

If ports you have installed depend on gcc8, MacPorts will prevent you from uninstalling it and tell you their names.

Hi, Trying to do that does not solve my problem :

[macp2034:anaconda3/include/python3.9] caux% port installed depends:gcc8
None of the specified ports are installed.

It seems none of my ports depend on gcc8...

Then, I uninstalled gcc8 (I already tried that but it didn't work) :

[macp2034:anaconda3/include/python3.9] caux% sudo port uninstall gcc8

If I then try the following command :

[macp2034:anaconda3/include/python3.9] caux% port list gcc8
gcc8                           @8.5.0          lang/gcc8

Seems to indicate gcc8 is still present, and indeed if I run sudo port upgrade outdated

I still have the same error.

Many thanks to help me to remove this gcc8 which I obviously do not need at all.

Hi again,

I am wondering if the best for me would not be to completely remove my MacPort installation and start again with a fresh new one. MacPort is installed on my system in :

# MacPorts Installer addition on 2022-04-27_at_13:43:04: adding an appropriate PATH variable for use with MacPorts.
setenv PATH "/opt/local/bin:/opt/local/sbin:$PATH"
# Finished adapting your PATH environment variable for use with MacPorts.

In /opt, I have :

[macp2034:~] caux%   ls /opt
X11/   edm/   local/

And in /opt/local/ :

[macp2034:~] caux% ls /opt/local
Library/ bin/     etc/     include/ lib/     libexec/ man@     sbin/    share/   src/     var/     www/
[macp2034:~] caux% 

Would it be safe to completely remove the dire /opt/local and make a fresh install of MacPort ?

Many thanks to let me know, cheers

Hi,

I am still stuck with this issue, please can someone give me some advice about removing the directory /opt/local and make a fresh install of MacPort ?

Replying to manulcaux:

If I then try the following command :

[macp2034:anaconda3/include/python3.9] caux% port list gcc8
gcc8                           @8.5.0          lang/gcc8

Seems to indicate gcc8 is still present,

port list tells you what is in the ports tree. It does not tell you what is installed. See wiki:FAQ#portlist.

If you wish to ​uninstall MacPorts, instructions are in the guide.
