Error building sqlcipher on Ubuntu 14.04 with undefined reference to 'readline'


#1

Running the following:
git clone https://github.com/sqlcipher/sqlcipher.git
cd sqlcipher
./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
make

Gives the error:
/tmp/ccPlapB4.o: In function one_input_line': shell.c:(.text+0x5be): undefined reference toreadline’
shell.c:(.text+0x5e0): undefined reference to add_history' /tmp/ccPlapB4.o: In functionmain’:

shell.c:(.text+0xc9f9): undefined reference to `write_history’
collect2: error: ld returned 1 exit status
make: *** [sqlcipher] Error 1

What additional steps do I have to run to get gcc to find readline? I checked the /usr/include/readline and there is a readline.h file present.

The output from the
./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"

Hi @andrbbtest

On your system you may need to install the readline library separately. Try the following to locate the correct package for your environment:

apt-cache search readline

Once you have identified the correct package, install it for your environment, then try adjusting your ./configure step to include -lreadline within the LDFLAGS.


#3

I’m running 64-bit Ubuntu, when I did the apt-cache search readline, the possible options for 64-bit were:
lib64readline-gplv2-dev - GNU readline and history libraries, development files (64-bit)
lib64readline5 - GNU readline and history libraries, run-time libraries (64-bit)
lib64readline6 - GNU readline and history libraries, run-time libraries (64-bit)
lib64readline6-dev - GNU readline and history libraries, development files (64-bit)

I ran:
sudo apt-get install lib64readline6
When installed fine.

The I ran:
./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto -lreadline"
And got this error:
checking build system type… x86_64-unknown-linux-gnu
checking host system type… x86_64-unknown-linux-gnu
checking for gcc… gcc
checking whether the C compiler works… no
configure: error: in /home/sludwig/320HD/gitrepo/sqlcipher': configure: error: C compiler cannot create executables Seeconfig.log’ for more details

Looking in the config.log I see this error:
configure:2913: gcc -DSQLITE_HAS_CODEC -lcrypto -lreadline conftest.c >&5
/usr/bin/ld: cannot find -lreadline
collect2: error: ld returned 1 exit status
configure: failed program was:
| /* confdefs.h */

Note the same “cannot find -lreadline” error is in the config.log file for when ./configure worked where the LDFLAGS were just set to -lcrypto.

Is there an environment setting I need for the gcc compiler to find readline.h?


#4

Hi @andrbbtest

I believe you will need to install lib64readline6-dev as well. Can you try that and rebuild SQLCipher?


#5

In the end I installed libreadline6-dev and now I’m able to build sqlcipher. @developernotes Thank you.

Hi @andrbbtest

We are glad to hear everything is building properly for you!
