If you get a checksum error on FreeFileSync_xx.x_Source.zip, please try to download this file manually from https://freefilesync.org before building.

The host for the source URL is hostile towards direct downloads and will randomly output the wrong content. In my experience, retrying once or twice is enough to make it work (don't forget to delete the source archive first !).

ERROR: The download program dlagent is not installed.

That worked, symen. Pretty strange behavior, that's the first time I get something like this!

I cannot perform the latest update:

==> Validating source files with sha256sums... FreeFileSync_10.15_Source.zip ... FAILED

(...)

==> ERROR: One or more files did not pass the validity check! Error downloading sources: freefilesync

@mozzi32 This one is weird. I can't even find Transaction.cpp in the source files. Did you post a comment for the wrong package ? :D

other mismatch for me

src/cpp/src/Transaction.cpp:128:84: attention: paramètre « providers_length1 » inutilisé [-Wunused-parameter] 128 | ->gint{ | ~~~~^~~~~~~~~~~~~~~~~ make: *** [Makefile:849: Transaction.o] Error 1 ==> ERROR: An error occurred in build (). Skipping

FYI: I had removed the workaround for v10.15 because it seemed to work fine without it (I had tried from different IP addresses). However it stopped working today (thanks @mozzi32 for the notice).

I put the workaround back, but in a separate DLAGENT script to make it less annoying (and a bit cleaner IMO). I re-used the script from freefilesync-bin.

@the_10 All you have to do is adding a browser User-Agent to your wget request header like this:

-U "Mozilla/5.0"

So it will be:

wget https://freefilesync.org/download/FreeFileSync_10.14_Source.zip -U "Mozilla/5.0"

@the_10 This has got something to do with freefilesync.org itself, of course you can download freefilesync source from their website yourself, but I will check to see if there is something to be done in order to download directly via curl.
