Doesn't build on musl - libc::malloc_trim is GNU-specific
ptrcnull opened this issue · 4 comments
Describe the bug
When building httm
with musl libc, for example on Alpine Linux, the build fails with the following:
error[E0425]: cannot find function `malloc_trim` in crate `libc`
--> src/exec/interactive.rs:104:27
|
104 | let _ = libc::malloc_trim(0);
| ^^^^^^^^^^^ not found in `libc`
error[E0425]: cannot find function `malloc_trim` in crate `libc`
--> src/exec/interactive.rs:172:35
|
172 | let _ = libc::malloc_trim(0);
| ^^^^^^^^^^^ not found in `libc`
To Reproduce
$ docker run --rm -it alpine:edge sh -c 'apk add cargo && cargo install httm@0.27.0'
Expected behavior
A additional target_env = "gnu"
guard before libc::malloc_trim
, both in httm itself and in the two_percent crate.
Additional context
httm
version: 0.27.0- OS: Alpine Linux edge
- Relevant filesystem/s: n/a
As I mentioned, malloc_trim
is also used in the two_percent
crate; the command I posted to reproduce the issue still fails (after changing the source to git HEAD instead of crates.io: cargo install --git https://github.com/kimono-koans/httm
)
error[E0425]: cannot find function `malloc_trim` in crate `libc`

As I mentioned,
malloc_trim
is also used in thetwo_percent
crate
Ooops, my mistake, will you check to see if the following fixes?: https://github.com/kimono-koans/httm/releases/tag/0.27.2
0.27.2
builds properly now, thank you!
