Bulat, why does SREP crash with small chunk size? e.g. -l8

Another issue. When I try to decompress an archive created by srep 3.93a, I receive following error.

ERROR: write error (disk full?) in compression algorithm srep:m5f:mem75%:l64

Drive C has 26GB of free space, and RAM is 32GB. Uncompressed file is 8.77GB.

1. such small chunk size isn't supported
2. try with srep 3.2

SREP 3.94 when ?

[Shelwien]

You can write it, its open-source :)

[msat59]

[External compressor:srep]
packcmd   = srep64   {options} -                   - <stdin> <stdout>
unpackcmd = srep -d {options} -                   - <stdin> <stdout>
;packcmd   = srep    {options} $$arcdatafile$$.tmp -         <stdout>

Is it still possible to use <stdin> <stdout> for latest SREP?

I couldn't make it work. It get following error:

ERROR: write error (disk full?) in compression algorithm srepstd:m5o

Is there any trick?

File is less than 3GB.

@msat59 : Afaik yes,but not recommended,but maybe im wrong. Never tried it.

@Bulat Ziganshin :
Do you have any news about FAnext ?

Is there any compiled version of FreeArc 0.67 linux? I can't find anything more than 0.666 for linux.

This archive includes various FreeArc addons, including .arc support for NSIS

What about FreeArc for linux? We're still missing the compile for 0.67

Please publish it when you can. Thanks in advance!

hi guys, someone takes away this doubt?
I extract multiple archives simultaneously within a folder with FreeArc using this command:

"Arc.exe" x -o+ -p"mypassword" -w.\ -dp"unpacked" "C:\Test\*.arc"

with the set of archives with the same format successfully extracted.

In the same way I'm interested in using "unarc.exe" and not FreeArc.exe, using the command line:

"unarc.exe" x -o+ -p"mypassword" -w.\ -dp"unpacked" "C:\Test\*.arc"

But I get the error that the archives are not read, how can I solve them, I miss some command line options or something else ???

@Bulat,
that´s the most viewed thread so far!

Hi ! i'm trying to compile Freearc for Linux, i found the source code in this github

https://github.com/phyxolog/FreeArc.git

The GNU/Linux i'm using is a Linux Mint 19.3 x86_64

This i what i did

git clone https://github.com/phyxolog/FreeArc.git
downloaded https://sourceforge.net/projects/p7z...rc_all.tar.bz2 and extracted the p7zip 9.04 sources into 7zip subdirectory of this directory
sudo apt-get install ghc ghc-prof libcurl4-gnutls-dev
sudo chmod +x compile*
./compile

Edited the file makefile and changed --march=i486 for x86-64 and mtune=prentiumpro for intel

And this are the errors i have

Follow exactly the UNIX-specific guidelines in readme.txt

In particular, package names on newer Linux distros may be different, you need ghc 6.10.4 and compatible 32-bit gcc version

x64 isn't supported by parts of C++ code, so you can build only x86 version (or try to remove all x64-incompatibale modules on your own)

newer GHC versions will not work, at least because they changed the exception handling scheme in ghc 7

and newer gcc versions will probably don't work with ghc 6.10

CLS is supported only on Windows, so just remove it from Compression/compile

[SolidComp]

You wrote it in Haskell? Is it more secure that way against malicious input?

[Bulat Ziganshin]

haskell used only for high-level code such as file handling. While for compression, freearc employs well-known existing C++ compression libraries such as lzma

Hi. Would you be willing to upload latest (SVN) source code for FreeArc? I've been looking for it for a while now for archival purposes.
