Cross compile subversion server (svnserve) from scratch for openwrt:

Unfortunately svnserve is not likely to be availabe in the chaos calmer (15.05) version of of openwrt.
This article describes how to cross compile svnserve (with very basic funtionality) from scratch with the toolchain.
It assumed the "mvebu" toolchain for the router Linksys WRT1200AC / WRT1900AC, but the procedures are similar for other routers.

1. Download the toolchain for WRT1200AC OpenWrt-Toolchain-mvebu_gcc-5.2.0_musl-1.1.11_eabi.Linux-x86_64.tar.bz2
2. Download subversion-1.6.23.tar.gz.
3. Download apr-1.2.12.tar.bz2
4. Download apr-util-1.2.12.tar.bz2
5. Download sqlite-amalgamation-3.6.13.tar.gz
6. Download zlib-1.2.8.tar.gz
7. Assume working directory is: /home/dev/svn_wrt1200ac.
   Put all source files above in /home/dev/svn_wrt1200ac/archive.
   cd /home/dev/svn_wrt1200ac
   
8. Add cross compiler in PATH.
   tar xjvf archive/OpenWrt-Toolchain-mvebu_gcc-5.2.0_musl-1.1.11_eabi.Linux-x86_64.tar.bz2
   
   export PATH=$PATH:/home/dev/svn_wrt1200ac/OpenWrt-Toolchain-mvebu_gcc-5.2.0_musl-1.1.11_eabi.Linux-x86_64/toolchain-arm_cortex-a9+vfpv3_gcc-5.2.0_musl-1.1.11_eabi/bin/
   
   Run arm-openwrt-linux-gcc to see if you can run the executable
   
   
9. Decompress the sources files in the right positions:
   tar xzvf archive/subversion-1.6.23.tar.gz
   tar xjvf archive/apr-1.2.12.tar.bz2
   tar xjvf archive/apr-util-1.2.12.tar.bz2
   tar xzvf archive/zlib-1.2.8.tar.gz
   tar xzvf archive/sqlite-amalgamation-3.6.13.tar.gz
   cd subversion-1.6.23
   ln -s ../sqlite-3.6.13/ sqlite-amalgamation
   
10. Compile zlib first
    cd ../zlib-1.2.8
    CC=arm-openwrt-linux-gcc ./configure --prefix=/home/dev/svn_wrt1200ac/finalBins/usr
    make install
    
    
11. Compile apr
    cd ../apr-1.2.12/
    ./configure --host=arm-openwrt-linux \
    ac_cv_file__dev_zero="yes" \
    ac_cv_func_setpgrp_void="yes" \
    apr_cv_process_shared_works="yes" \
    apr_cv_mutex_robust_shared="no" \
    apr_cv_tcp_nodelay_with_cork="no" \
    ac_cv_sizeof_struct_iovec="8" \
    apr_cv_mutex_recursive="yes" \
    --prefix=/home/dev/svn_wrt1200ac/finalBins/usr
    
    patch -p 0 include/apr.h
    
    Copy and paste the following, and then press Ctrl+D

    Start compile.
    make install
    
    
12. Compile apr-util
    cd ../apr-util-1.2.12/
    cd xml/expat
    ./configure --host=arm-openwrt-linux --prefix=/home/dev/svn_wrt1200ac/finalBins/usr
    make install
    
    cd ../../
    ./configure --host=arm-openwrt-linux --with-apr=/home/dev/svn_wrt1200ac/finalBins/usr \
    --with-expat=/home/dev/svn_wrt1200ac/finalBins/usr \
    --prefix=/home/dev/svn_wrt1200ac/finalBins/usr
    make install
    
    
13. Compile subversion
    cd ../subversion-1.6.23
    
    ./configure --host=arm-openwrt-linux \
    --with-zlib=/home/dev/svn_wrt1200ac/finalBins/usr \
    --with-apr=/home/dev/svn_wrt1200ac/finalBins/usr \
    --with-apr-util=/home/dev/svn_wrt1200ac/finalBins/usr \
    --prefix=/home/dev/svn_wrt1200ac/finalBins/usr \
    --without-berkeley-db
    
    make install
    
    
14. Making tarball and transfer to router.
    cd ../finalBins
    tar -czvf svn1.6.23_wrt1200ac_finalBins.tar.gz usr/lib/lib*so* usr/bin
    
    Transfer the svn1.6.23_wrt1200ac_finalBins.tar.gz to router. Assume /tmp/svn_wrt1200ac_finalBins.tar.gz. e.g.:
    scp svn1.6.23_wrt1200ac_finalBins.tar.gz root@192.168.1.1:/tmp/
    
    In router, decompress:
    cd /
    tar -xzvf /tmp/svn1.6.23_wrt1200ac_finalBins.tar.gz
    

To setup svn server:
(Reference: https://forum.openwrt.org/viewtopic.php?id=11693)
mkdir /tmp/svn_repos
svnadmin create --fs-type fsfs /tmp/svn_repos

Added 3 lines to setup svn password:
In /tmp/svn_repos/conf/svnserve.conf, uncomment the folowing 3 lines
anon-access = read
auth-access = write
password-db = passwd

Add in /tmp/svn_repos/conf/passwd, password for "yylam"
To restart svn server is in /etc/rc.local
/usr/bin/svnserve -d -r /tmp/svn_repos

From OpenWrt forum: Looks like the same SVN package from the OpenWRT old_packages git repository. To reactivate the old_packages, add the following line to your feeds.conf file.

src-git old_packages git://git.openwrt.org/packages.git

hen, once you run scripts/feeds update old_packages; scripts/feeds install -a -p old_packages to update your OpenWRT, execute make menuconfig and enable the subversion package under Network --> Version Control Systems and then recompile your OpenWRT. If you don't like to add the old_packages, then either port the subversion package from the old_repository to OpenWRT GitHUB or wait for someone else to do this for you.
