Google Earth 5.0, Ubuntu 9.04 (Jaunty Jackalope) – symbol lookup error: libssl.so.0.9.8, undefined symbol: EVP_idea_cbc, libcrypto.so.0.9.8 bug
I have tried to install Google Earth on Ubuntu 9.04 (Jaunty Jackalope) today and I came across a simple bug.
After installation, Google Earth was not able to communicate using SSL. It gave me this error message:
/usr/lib/googleearth/googleearth-bin: symbol lookup error: /usr/lib/googleearth/libssl.so.0.9.8: undefined symbol: EVP_idea_cbc
The simple bug-fix is to rename/copy libcrypto.so.0.9.8 shared library into libcrypto.0.9.8, as I have found only on some French websites.
Use sudo if you’re not logged in as root. You can also probably use mv instead of cp. You can run for example these commands:
root@v-teq-laptop:~$ cd /usr/lib/googleearth/ root@v-teq-laptop:/usr/lib/googleearth$ cp libcrypto.so.0.9.8 libcrypto.0.9.8
Everything should run now, just enjoy Google Earth 
DDD (gdb): No source: ../sysdeps/x86_64/elf/start.S: No such file bug; Missing XKeysymDB file bug
I came across a strange bug, or better said, strange behavior of ddd today. I have tried to debug my program and I have got this error dialogue:
DDD: No source
/home/v-teq/…/sysdeps/x86_64/elf/start.S: No such file or directory
Missing XKeysymDB file
I have tried to find out where was the problem:
v-teq@v-teq-laptop:~$ ddd --check-configuration Checking for XKeysymDB... (none) Warning: The `XKeysymDB' file is not in the default X file search path. If ddd was not compiled on this machine, ddd may not run properly (lots of warnings for unknown keysym names). and install it into your X project root (typically `/usr/lib/X11') or have the XKEYSYMDB environment variable point at it.
But as you can see, I found another error message that was ddd printing out – it couldn’t find XKeysymDB file. The solution was quite easy – only to find the XKeysymDB file in my /usr directory, because default /usr/lib/X11 path doesn’t exist anymore on my Debian based machine.
v-teq@v-teq-laptop:~$ find /usr -name XKeysymDB /usr/share/X11/XKeysymDB
So the answer was /usr/share/X11/XKeysymDB in my case.
Now it’s easy to set environment variable and get ddd working again:
v-teq@v-teq-laptop:~$ XKEYSYMDB=/usr/share/X11/XKeysymDB ddd --check-configuration Checking for XKeysymDB... /usr/share/X11/XKeysymDB
You can set variable pernamently of course (or you can echo this line into your ~/.bashrc or such file).
For sh, ksh or bash:
export XKEYSYMDB="/usr/share/X11/XKeysymDB"
For csh:
setenv XKEYSYMDB "/usr/share/X11/XKeysymDB"DDD: No source: ../sysdeps/x86_64/elf/start.S
Now back to the first problem – error dialogue that said I didn’t compiled debugging information to my executables, so debuggers (ddd, gdb) weren’t able to use symbols from source files.
Take care if you have compiled your binary files (executables or libraries) really with debugging information (eg. -g option in gcc). My problem was, that my Makefile created executables from libraries with -g option, but libraries themselves were compiled without this option automatically (there was no rule to make *.o files in Makefile).
So my advice is to double check your Makefile, or command line if you’re compiling project manually, if you have really set the -g option. For example:
gcc -g -o main main.c
Or if you want to create *.o file before linking to final executable, don’t forget to check -g option in both cases:
gcc -g -c -o main.o main.c gcc -g -o main main.o
You can also add something like that to your Makefile to compile *.o files with -g debugging option automatically:
CC=gcc CFLAGS=-g %.o: %.c $(CC) $(CFLAGS) -c $< -o $@
