[SETUP] issue making it default linker about mold

[rui314]

I'm closing this issue as it seems to have been resolved.

Please try to rename mold in the same directory instead of moving to somewhere else, just like this:

$ make
$ mv mold mold2
$ ./mold2 -run make

Then, verify that your mold is built with mold by running readelf -p mold.

well, yes, mold is successfully linked using mold:

[ 0] GCC: (Ubuntu 10.2.0-5ubuntu1~20.04) 10.2.0
[ 2b] clang version 10.0.0-4ubuntu1
[ 4b] mold a02fc7edb64b3fe7a58360123fab1ed3069b42f3

But by default the applications i compile are not
[ 0] GCC: (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

What is your application?

Oh, just a simple hello world, one file

Hmmm, same deal with multiple files to having run
cc file1 file2 -o output

[rui314]

You have to tell cc to use mold as a linker. One way of doing it is adding -fuse-ld=<absolute-path-to-mold> to cc (if it doesn't work with your cc, try clang instead of cc). The other way is to run your cc as a subcommand of mold, as shown below

path/to/mold -run cc file1 file2 -o output

Ohh, alright, sorry i got the impression that by running that
(/mold -run make) it would automatically replace ld
