FreeFileSync Forum

I restarted the android app that acts as a ssh server as well as freefilesync.
After this, performance of freefilesync became equivalent to scp.

I was trying to sync files with freefilesync SFTP (from PC to Android). I found it rather slow: between 150-700kB/s.

I also tried with scp and it is much faster, up to ~2MB/s

scp -v -P <port> -i <private-key-file> <source> <user@ipv4>:/

<source> 11% 44MB 1.7MB/s 03:21 ETA


This was with a ...

I would also be interested in such a feature.

Instead of a button to run them individually, I would suggest checkboxes next to each pair, that could be checked/unchecked whether the pair needs to be synced.

This would help also with my other request at https://freefilesync.org/forum/viewtopic.php ...

As of today, the path to the key-file in the SFTP configuration is always an absolute path.

This can be problematic when sharing the ffs-gui file accross multiple OS (eg. linux ←→ windows), or when the mount-point of the ffs-gui file changes

Would it be possible to have a relative path instead ...

Thank you for the suggested workflows. The first one would fit.

As per:
But regarding left-right pairs: obviously c:\path_to_my_files vs /mnt/windows_c/path_to_my_files will not adapt automatically.

I didn't expect automatic transformation between c:\path_to_my_files and /mnt/windows_c/path_to ...

Thank you for the suggestion.

What if I change some configuration/setting of the origial ffs_gui file? My guess is that it will not feed the copy automatically with the changes, and that I will have to replicate all changes to each copy ffs_gui copy manually. This is cumbersome, that's why I ...

I have a configuration file with
- on the left a local path on a local disk
- and on the right a local path to a USB stick (for example) with mount point /media/user/VOLUME_NAME

I would like to use the same configuration but with another USB stick (with volume name = USB_STICK2). The path would ...

Did you try building from the Debian source package?
https://tracker.debian.org/pkg/freefilesync

You could also try to build from tag "debian/13.3-2_bpo12+1_1" from the Debian VCS repository . It should build on bookworm without any change.

Or else try taking the source package from xtradeb's PPA ...

Could this be related to SELinux?

According to your logs, command is run with the correct user.

I don't know for SuSE, but in Debian, there is a field to set the username under which the command should be run. Is "username" field of your cron file correctly set?

# .---------------- minute (0 - 59)

BTW, I noticed that in the About dialog, only the last Show() must be kept. Having both leads to corruption in the dialog (at the location of the donation text + image)

I actually had the same problem with gtk LDFLAGS which are missing at link time, so I had to add them with

LDFLAGS += `pkg-config --libs gtk+-3.0`


Would you add them to the Makefile please?

Error was:
/usr/bin/ld: /tmp/cc6adrRa.ltrans115.ltrans.o: undefined reference to symbol 'gtk_css ...

Since the file (zen/zlib_wrap.cpp) that uses it in your code base doesn't apparently depend on wx-widget neither on gtk, I thought it had to be present in the Makefile. But I could be wrong.

Thank you for your reply. Apparently on my system it is not:


$ wx-config --libs std, aui, richtext --debug=no
-L/usr/lib/x86_64-linux-gnu -pthread -lwx_gtk3u_aui-3.2 -lwx_gtk3u_richtext-3.2 -lwx_gtk3u_xrc-3.2 -lwx_gtk3u_html-3.2 -lwx_gtk3u_qa-3.2 -lwx_gtk3u_core-3.2 -lwx_baseu_xml-3.2 -lwx_baseu ...

Hi Zenju, when trying to build freefilesync I noticed that the LDFLAGS for zlib are missing. May I suggest you to add these lines to your Makefile (both FFS & RFS). They could be placed near the equivalent lines for the other libraries.


CXXFLAGS += `pkg-config --cflags zlib`
LDFLAGS += `pkg ...

Dear Zenju, I have been investigating this a bit since I run on KDE, which caused trouble with gtk3 at the time of 12.1.

Actually, I found that calling only Show() but not Hide() as code currently does since 12.1:
- doesn't create the "freeze/hang" on KDE that appeared in 12.1
- fixes the size of ...

What about using one of these (as per Strategies for Exception Handling), for minimal exception handling?
- wxApp::OnExceptionInMainLoop()
- wxApp::OnUnhandledException()

tcw4950, you can find a package of FreeFileSync 13.3 for Ubuntu 20.04 (focal) on my PPA.

Hmm 20.04 (focal) you said? Hmm... Sorry I wrote for 22.04 (jammy). But the process would be the same.
By the way, for jammy, there is 13.1 on a PPA.

You can start from this page , the bottom of which you have "Other versions of 'freefilesync' in untrusted archives." It show that for jammy (22.04) there is a PPA providing version 11.25-1~xtradeb1. (2022-08-31)

If you feel like building your package from the sources, you can get a working ...

As per: https://repology.org/project/freefilesync/history

2023-02-09 07:03 Raspbian Testing has caught up with the newest version

By that time it was 12.0.
12.4 may arrive soon

If this is specific to 12.1 you might want to have a look at this thread: viewtopic.php?t=10103

BTW, there is a link to a patch in it (if you compile from sources)

Zenju, reverting the change you mention apparently removes the issue (still built with GTK3).

For anyone interested, a patch for this revert is available here: https://salsa.debian.org/bastif/freefilesync/-/blob/debian/latest/debian/patches/revert_buggy_gtk3_change_in_12.1.patch

It seems I have a similar problem on debian with KDE, when built from source.
BTW, the Makefile still references gtk2, is this as expected or should it be gtk3 now?

Hello,

In 12.0 there are two new files: zen/argon2.cpp & zen/argon2.h

While you are a copyright holder for argon2.h, you are not mentioned at all in argon2.cpp although you made changes there. You actually reference putty copyright holder only.

Can you confirm that the copyright header is as ...

Hello Zenju,

Would you provide the AppStream Metadata? I think its better if this file is provided by you rather than each distribution having its own. That way you can have control on the value of the fields and all distros would share the same.

More info can be found here.

Hello Zenju & all,

I'm having this error when building freefilesync on s390x architecture:


base/db_file.cpp:51:39: error: static assertion failed

Looks like this one can be fixed by adding -latomic to the LDFLAGS on mipsel architecture.
Not sure if this is the correct way to fix this though.
