Hi,
this package is for linux emulation for support application with dependent
for libusb.
Thank you M.
Comment 1 Tijl Coosemans freebsd_committer 2020-09-22 08:37:04 UTC
Linux libusb doesn't work on FreeBSD.  There's devel/linux_libusb which compiles FreeBSD libusb for Linux.  Can you give that port a try?

I try for CCS9.3.0.00012_linux-x64 studio but still have 
missing dependency

Date: Tue Sep 22 13:41:55 UTC 2020
New revision: 549593
URL: https://svnweb.freebsd.org/changeset/ports/549593

Log:
  - Build 64-bit version on amd64.
  - Add run dependency on linux_base.
  - Remove -march from CFLAGS because gcc 4.8 does not know recent cpu types.

I've committed an update to devel/linux_libusb.  Can you give that a try?
Comment 5 Alex S 2020-09-26 14:07:45 UTC
I'm not exactly sure COMPAT_32BIT does there, but it definitely does not build the 32-bit version of the library.

New revision: 550227
URL: https://svnweb.freebsd.org/changeset/ports/550227

Log:
  Add a direct build dependency on linux_base instead of relying on devtools
  to pull it in.  This guarantees that the version constraint set in
  Mk/Uses/linux.mk is taken into account.

  Compile with --sysroot=${LINUXBASE} such that gcc doesn't pick up headers
  from /usr.

  Build the 32 bit library on amd64 with -m32 such that it's actually a 32 bit
  library.  This must have become broken long time ago when 64 bit linux
  support was added and the compiler became 64 bit. [1]

Thank you, Tijl. Do you think it's safe to also symlink libusb-1.0.so.0 to libusb.so.3? The [FreeBSD libusb] code seems to suggest so at least.

Yes, it should work.  Do you have a way to test it?

Well, Linux Steam + Steam controller. In fact, I already played with it a bit (both literally and figuratively) a while ago, there were some annoying crashes:

*** Error in `/home/steam/.steam/steam/ubuntu12_32/steam': double free or corruption (out): 0x2d9796d0 ***
======= Backtrace: =========
/lib/libc.so.6(+0x79aad)[0x217a3aad]
/lib/libusb.so.3(libusb20_dev_free+0x26)[0x21951206]
/lib/libusb.so.3(libusb_unref_device+0x53)[0x2194bd53]
/lib/libusb.so.3(libusb_free_device_list+0x3b)[0x2194bf6b]
...

and the whole thing is incredibly niche, so I put this on the back burner.

(In case you don't mind being utterly bored, my personal list of not very exciting Steam issues is available at https://github.com/shkhln/linuxulator-steam-utils/wiki/Home-improvement-ideas. Mostly points to this bug tracker anyway.)

Log:
  Remove libusb.so symbolic link because it belongs in a -devel package.
  Add libusb-1.0.so.0 symbolic link because FreeBSD libusb implements that
  API too.
