How to install TrueCrypt 4.3a on Fedora 7

Submitted by Yousif on Sat, 09/06/2007 - 7:02pm.

We are going to compile TrueCrypt from source so first grab TrueCrypt's source code.

Extract the source code and navigate to the Linux folder

tar xfz truecrypt-4.3a-source-code.tar.gz
cd truecrypt-4.3a-source-code
cd Linux

Truecrypt needs to compile a kernel module during the build process. Unfortunately the kernel headers included with Fedora 7 (in the kernel-devel package) are missing the dm.h header file which is needed for compiling the kernel module.

We need to download the source RPM for the kernel and install it. I am using the release version of Fedora 7 so the rpm command would be...

su
rpm -ivh http://mirrors.kernel.org/fedora/releases/7/Fedora/source/SRPMS/kernel-2.6.21-1.3194.fc7.src.rpm
rpmbuild -bp --target=noarch /usr/src/redhat/SPECS/kernel-2.6.spec

This is roughly a 45MB download. Once we are done installing the source RPM we edit the build.sh file located in TrueCrypt's Linux folder.

Change the line

KERNEL_SRC=/lib/modules/$KERNEL_VER/source

to

KERNEL_SRC=/usr/src/redhat/BUILD/kernel-2.6.21/vanilla

save and run build.sh as root to start the build process

su
./build.sh

still logged in as root run the install script and modprobe the kernel module

./install.sh
/sbin/modprobe truecrypt

If the install script complains that modprobe is not found export the path to sbin to the path variable as follows

export PATH=/sbin:$PATH

We successfully installed truecrypt!

Didnt work for me...

Submitted by Anonymous on Sun, 10/06/2007 - 5:59pm.

/usr/src/redhat/BUILD/ is empty after installation of source. Used rpmbuild --rebuild command and source is now there.

Didnt work for me 2...

Well, I quickly found out that that directory disappears when the rpmbuild finishes so, doing this from a Terminal in superuser mode, terminated the rpmbuild after the vanilla directory appeared and rpmbuild had moved onto another file/folder by closing the window. It left the vanilla directory intact and installation of truecrypt was perfect. Thanks for getting me started in the right direction.

Ops! Forgot to add the rpm

Submitted by Yousif on Tue, 12/06/2007 - 11:54am.

Ops! Forgot to add the rpm build command :/
It's

rpmbuild -bp --target=noarch /usr/src/redhat/SPECS/kernel-2.6.spec

I edited the article with the rpmbuild command. Thanks for letting me know about this.

modprobe truecrypt error

Submitted by Anonymous on Wed, 27/06/2007 - 6:28pm.

Hi. I followed the article and almost everything works fine.
In the modprobe command I got the message:
FATAL: Error inserting truecrypt (/lib/modules/2.6.21-1.3228.fc7/extra/truecrypt.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Do you know what is that message. Did you get that message?

Thanks,

I get right to the end of the installation and get this error:

I'm assuming that the second error is a result of the first. Any ideas how to fix this?

I am on the same boat ...

I am on the same boat ... keep getting this error after following the instructions very closely. I checked my gcc environment and even made sure we had a plain install. I even tried compiling truecrypt using the makefile and the issue remains. I am installing on Ubuntu instead :(

Truecrypt does not work with Fedora 7 kernel 2.6.22

Hi,

your procedure does not work with the new kernel 2.6.22 as the rpm package is available only for 2.6.21.
Do you have any suggestion?

Thanks,

You've probably worked it out by now but if you Google "download kernel-2.6.21.1.41.fc7.src.rpm" you'll get several hits for it, but please check my typing.

No, it doesn't work with kernel-2.6.22.5-76.fc7.src.rpm

Problems with using comments

Submitted by abejarano on Tue, 04/09/2007 - 8:18pm.

Using Konqueror to comment, I was asked to answer a simple math question. My answers were always wrong?? Anyway that is the message I got when I tried to preview or post. With firefox no questions are asked and it's easy to post a comment. Probably something to do with Java script which I keep off Konqueror.

Thanks! This post was very useful to me.

fatal error on modprobe

Thank you for a useful step-by-step guide. I am trying to open some Windows truecrypt volumes in Linux.

Like several other readers have written above, at the end of the above procedure I get the following error in response to "modprobe truecrypt":

2.6.23 kernel

Submitted by Anonymous on Thu, 01/11/2007 - 8:20pm.

Many thanks for the guide. I must bookmark it as I depend on it every time a new kernel update is released and then spend a while wondering why truecrypt doesn't work.

A couple of tips for anyone struggling...

For the 2.6.23 kernel I had to use the following to get the source rpm...

rpm -ivh http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/linux/updates/7/SRPMS/kernel-2.6.23.1-10.fc7.src.rpm

Also the 4.3a source doesn't compile against 2.6.23, but someone has posted a patch here...

http://andika-lives-here.blogspot.com/2007/10/truecrypt-43a-patch-for-kernel-2623-rcx.html

For those not up on patching (like me), I just copied the patch text down to the end of the last line and pasted it into a file (e.g. patch-2.6.23) and put that in the kernel directory under the truecrypt linux source, then ran 'patch -l -p0 < patch-2.6.23' from that directory.

Seemed to build then.

Phew. Whilst linux is certainly getting there with usability there are still a few little things like this which requires getting dirty. Really shouldn't have to mess about with kernel stuff, but anyway. What we really need is a truecrypt fedora package on livna or somewhere similar (any idea how you go about requesting that?).

Thanks for posting your

Submitted by Yousif on Fri, 02/11/2007 - 7:36am.

Thanks for posting your tips. I too believe there should be a truecrypt fedora package. I remember trying to make one once sometime ago but I was put off by the bureaucracy of becoming a package maintainer and the effort needed to maintain updates and creating a new kernel module every time a new kernel appears on the official repository. check out this page on livna if you're interested (http://rpm.livna.org/rlowiki/Contributors)

I posted the above tip (I can't seem to create an account here so I'm coming up anon). Anyway, so I just repeated what I did but with the updated kernel source.

The patch still seems to work, though I didn't re-run the patch as I still had the patched truecrypt source.

Still I cannot install it properly. This is what I do:
