Installation on Linux is well documented.
wget https://www.scootersoftware.com/bcompare-22.214.171.12495.x86_64.rpm su rpm --import https://www.scootersoftware.com/RPM-GPG-KEY-scootersoftware yum install bcompare-126.96.36.19995.x86_64.rpm
On my Fedora 27 box, I found the launcher bash
/usr/bin/bcompare exits with a return code of 1, if the linker cannot resolve all dependencies.
BC_LIB=/usr/lib64/beyondcompare export BC_LIB EXEC=$BC_LIB/BCompare #check to see if we have all of the shared libraries. CHECK=`ldd $EXEC | grep "not found" | wc -l` if [ "$CHECK" -ne "0" ]; then echo Some Shared Libraries were not found ldd $EXEC exit 1 fi
Dumping out the shared libs
BCompare depends on:
$ ldd /usr/lib64/beyondcompare/BCompare linux-vdso.so.1 (0x00007ffe9b023000) librt.so.1 => /lib64/librt.so.1 (0x00007f5da4fca000) libbz2.so.1.0 => not found lib7z.so => not found libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f5da4dac000) libc.so.6 => /lib64/libc.so.6 (0x00007f5da49f6000) libdl.so.2 => /lib64/libdl.so.2 (0x00007f5da47f2000) libQt4Pas.so.5 => not found libX11.so.6 => /lib64/libX11.so.6 (0x00007f5da44b4000) libz.so.1 => /lib64/libz.so.1 (0x00007f5da429d000) /lib64/ld-linux-x86-64.so.2 (0x00007f5da51d2000) libxcb.so.1 => /lib64/libxcb.so.1 (0x00007f5da4075000) libXau.so.6 => /lib64/libXau.so.6 (0x00007f5da3e71000)
Out of the tree missing libs
libbz2.so.1.0 seems to be the problem child, as
libQt4Pas.so.5 are distributed with bcompare and added to the
LD_LIBRARY_PATH by the start script. It turns my Fedora box comes with
libbz2.so.1.0.6, and can be symlinked as
sudo dnf install bzip2-libs bzip2-devel sudo ln -s `find /usr/lib64/ -type f -name "libbz2.so.1*"` /usr/lib64/libbz2.so.1.0
Beyond Compare supports many version control systems. For Git simply bind the
mergetool configurations (
~/.gitconfig) to bcompare:
git config --global diff.tool bcompare git config --global merge.tool bcompare
Now from Git, bcompare will be invoked with all the appropriate command line parameters:
git difftool myfile.ext git mergetool myfile.ext
Not always obvious to new users, there are several optional (but powerful) plug-ins tucked away for download. Some favourites, that have saved my bacon on many occassions:
- XML Tidy Sorted will normalise both source and target files by, running XML Tidy and then ensuring that all elements and attributes alphabetically sorted. This is especially wonderful, if you are comparing XML produced by differing libraries/platforms/langs.
- Java Formatted Class decompiles and formats
classfiles into plain text (depends on the Jalopy and Java Class rules).
- MS Excel Merge supports diff (read) and merge (write) operations. So good, in a world where Excel is pandemic.
- PDF converts PDF into plain text for diffing. I mostly fire this up when non-technical folk (e.g. PMs or BAs) provide multiple versions of requirements, with no change log.
- MS Word converts doc and docx into plain text for diffing. Again, I mostly fire this up when non-technical folk (e.g. PMs or BAs) provide multiple versions of requirements, with no change log.
