How to compile statically linked SSHFS?

[Advrk Aplmrkt]

Hello,

As I attempt to build a patched SSHFS 2.4 with the remote_dmask and remote_fmask options developed here, I would also like to build it into a statically linked portable binary so that I can easily use it on all my machines.

However, when I use the "-static" gcc option, I get an error saying "configure: error: C compiler cannot create executables". I've also pasted the corresponding part of config.log here.

Since the Fuse for OS X website distributes a .pkg installer for SSHFS, surely there is a way to build a statically linked portable SSHFS?

Any instructions would be great, thank you!

After you ran make to build a non-static version of SSHFS run the following command in the source directory:

gcc -D__DARWIN_64_BIT_INO_T=1 -D__FreeBSD__=10 -D_FILE_OFFSET_BITS=64 -D_REENTRANT -I/usr/local/include/osxfuse/fuse -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include -I/opt/local/include -DDARWIN_SEMAPHORE_COMPAT -Wall -W -o sshfs sshfs-sshfs.o sshfs-cache.o -pthread -L/usr/local/lib -losxfuse /opt/local/lib/libglib-2.0.a /opt/local/lib/libgthread-2.0.a /opt/local/lib/libiconv.a /opt/local/lib/libintl.a -framework Carbon

This relinks the SSHFS binary using only static libraries. Please note, that this will only work if you installed all the necessary libraries through MacPorts to /opt/local.

Hello,

I tested the resulting binary on another machine, and yes it worked! Just one more thing: I was trying to build an Universal Binary for i386, x86_64, and ppc architectures, but after running that command there is only x86_64 left. Is there a way to run this process so that I end up with a statically linked Universal Binary of SSHFS, just like the one distributed by the package installer?

Sorry I have so many questions, I am rather new to all this. Thank you for your patience!

[Benjamin Fleischer]

To create a static universal binary (ppc, i386, x86_64) you need to install universal version of all needed libraries, then run the following command in the source directory:

autoreconf -i

CFLAGS="-DDARWIN_SEMAPHORE_COMPAT -arch i386 -arch x86_64 -arch ppc" ./configure --prefix=/usr/local --disable-dependency-tracking

make

gcc -D__DARWIN_64_BIT_INO_T=1 -D__FreeBSD__=10 -D_FILE_OFFSET_BITS=64 -D_REENTRANT -I/usr/local/include/osxfuse/fuse -I/opt/local/include/glib-2.0 -I/opt/local/lib/glib-2.0/include -I/opt/local/include -DDARWIN_SEMAPHORE_COMPAT -arch i386 -arch x86_64 -arch ppc -Wall -W -o sshfs sshfs-sshfs.o sshfs-cache.o -pthread -L/usr/local/lib -losxfuse /opt/local/lib/libglib-2.0.a /opt/local/lib/libgthread-2.0.a /opt/local/lib/libiconv.a /opt/local/lib/libintl.a -framework Carbon

In addition to the universal libraries you will need Xcode 3.2 for building PPC binaries.

I just compiled it per your instructions, and tested it both on my
Intel Core i7 MacBook Pro and on an old PowerMac G4 - both worked! So
that I can "learn how to fish", if anyone can tell me resources to
learn what all those commands mean that would be great.

Thank you so much for your help and patience, I very grateful! Now I
just need to go on and figure out the permissions issues I am having
for mounted SSHFS volumes...

Hi... I have been having the same problem trying to complie sshfs

Since you have it working correctly with the remote_dmask option would you be able to send me a copy?

I would really appreciate it.

Thanks.

Hello!

Yes I finally got it to work, but with some problems running it,
especially as part of MacFusion. Which version of Mac OS X are you
running? I tested it from 10.5 through 10.7 on both PPC and Intel
machines, and here is the list of runtime problems:

When you test it can you please let me know if you run into similar problems???

Here is the link to the statically linked sshfs binary:

Please let me know how it works for you, thanks!

[James Rascoe]

Thanks... It works GREAT... thes options worked just fine.

-o remote_dmask=775 -o remote_fmask=775

To make it run in MacFusion all you need to do do a "show package contents" on your MacFusion app.

Then... go to the Contents/Plugins/sshfs.mfplugin/Contents directory

rename the old sshfs-static and then put yours in that directory and call it sshfs-static

After that you will be fine!

Thanks again.. you should publish this as a lot of people are looking for it.

Jim

Glad it worked! But how are binaries like this usually "published"?

I tried replacing the stock sshfs-static in the MacFusion application
with mine, but its got problems:

On the Mac OS X 10.5 machine, the volume mounts, but shows it has
"zero bytes" free space, and I was unable to upload any files to it!
(opening, editing, and saving existing files seemed fine)

On the Mac OS X 10.6 machine, I got this error when I try to mount the
volume: "Could not mount filesystem: Authentication failed." Looks
like this is the part of the log that shows the problem:

(SSHServerFS, [volume name], 2012-07-12 13:28:35) debug1:
Authentications that can continue:
publickey,gssapi-keyex,gssapi-with-mic,password
debug1: Next authentication method: publickey
debug1: Trying private key: /Users/[my user]/.ssh/id_rsa
debug1: Trying private key: /Users/[my user]/.ssh/id_dsa
debug1: Next authentication method: password
debug1: read_passphrase: can't open /dev/tty: Device not configured
(SSHServerFS, [volume name], 2012-07-12 13:28:36) debug1:
Authentications that can continue:
publickey,gssapi-keyex,gssapi-with-mic,password
debug1: No more authentication methods to try.
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

On the Mac OS X 10.7 machine, the volume was mounted successfully, and
most operations worked (such as creating, deleting, and modifying most
files). However, there are some strange permissions issues. For
example, Micro$oft Office 2011 applications like Word or Excel insists
on opening documents on the volume as read-only, and complains about
no permissions when trying to save to, or overwrite a file.

If anyone has suggestions I am all ears. Thanks!
