I am using a custom, portable build system that sets up the
environment, automates the
builds and handles install and uninstall of packages to a specified
location (in this case
within my home directory). The build system settings include
CC=musl-gcc, CPP=musl-gcc and
CFLAGS and LDFLAGS are set to only point to the paths where the musl
include and library files
are located. I'm also use -static.
Some of the applications, like diffh, diction, bzip2 are building and
running fine with musl.
If I check objdump -p, I see a different library when built with musl
than I do when I build
them with gcc.

Not seeing any patches referenced for xz:

The applications that are showing errors on my system include programs from xz,
wavpack, libpaper and speex.
Some programs do appear to be running, so likely it is something else.

Am not very familiar with strace, but I ran it on some of the programs
that were displaying errors.
The stderr results from using strace on wavpack were:
execvc ("./wavpack, ["./wavpack"],[/* 30 vars */]) = -1 EIO
(Input/output error)
dup(2) = 3
fcntl64 (3,F_GETFL) = 0x8001 (flags
O_WRONLY|O_LARGEFILE)
close(3) = 0
write (2, "strace: exec: Input/output error"..., 33 strace: exec:
Input/output error
) = 33
exit_group(1) = ?
The other programs that displayed the same error had very similar
output using strace.
Thanks.
Sincerely,
Laura
