I'm trying to install something using the 'make' command, however it gives me the fatal error:tcl.h no such file or directory. I'm new to linux, can anyone help me?

This means you're missing the tcl development files. The easiest way to check is to go to: http://packages.ubuntu.com/ and put "tcl.h" in the "search contents of packages" field. If you do this you'll find that tcl.h can be found in a number of packages you'll want to install one of those:

sudo apt-get install tcl8.6-dev

  • when i use sudo apt-get install tcl8.6-dev, it says: E:Unable to locate package tcl8.6-dev E:Couldn't find any package by regex 'tcl8.6-dev' – Goncalo Oct 27 '13 at 20:41
  • also, it says i have the newest version of tcl8.5-dev – Goncalo Oct 27 '13 at 20:42

Once you have a Tcl dev package installed, you'll then possibly come across the code expecting tcl.h to be in /usr/include/, but in order to facilitate multiple versions of Tcl being installed, Ubuntu places tcl.h in /usr/include/tcl/ - note the extra directory level.

Replacing: #include <tcl.h> with #include <tcl/tcl.h> in the source code you're trying to build should get around this.

    Instead of changing the code, you can change the include path of the compiler: add the option "-I/usr/include/tcl" to the compilation. – Erel Segal-Halevi May 12 '20 at 07:06
  • Don't change the code or the compiler flags! Why don't you just install tcl-dev package? This one is immediately found as it placs headers in /usr/include. :) – 71GA Aug 19 '21 at 11:57

    @71GA That may have changed since 20.04 a.k.a Focal (which is what's running on the box I've just check on), but tcl-dev on 20.04 placed tcl.h in /usr/include/tcl. If it had done as you say, I'd not've made my original comment :)

    20.04 creates a symlink: ❯ ls -l /usr/include/tcl{,.h} ls: cannot access '/usr/include/tcl.h': No such file or directory
    lrwxrwxrwx 1 root root 6 Feb 23 2019 /usr/include/tcl -> tcl8.6

    Gah, no formatting in comments :(

Happened to me, when trying to manually install python3.9 and fixing tinker import error Error:ModuleNotFoundError: No module named '_tkinter'

Then, i came to know, when you try to manually configure, you have to pass additional arguments.

./configure --with-tcltk-includes="-I/Library/Frameworks/Tcl.framework/Headers -I/Library/Frameworks/Tk.framework/Headers" --with-tcltk-libs="/Library/Frameworks/Tcl.framework/Tcl /Library/Frameworks/Tk.framework/Tk"
make

As, labarna mentioned you can search on ubuntu packages and install those. Then after that while downloading correct package, it still gave another another.

gcc -fPIC -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Werror=implicit-function-declaration -fvisibility=hidden -I./Include/internal -DWITH_APPINIT=1 -I./Include -I. -I/usr/include/x86_64-linux-gnu -I/usr/local/include -I/root/fix/Python-3.9.11/Include -I/root/fix/Python-3.9.11 -c /root/fix/Python-3.9.11/Modules/_tkinter.c -o build/temp.linux-x86_64-3.9/root/fix/Python-3.9.11/Modules/_tkinter.o -I/Library/Frameworks/Tcl.framework/Headers -I/Library/Frameworks/Tk.framework/Headers /root/fix/Python-3.9.11/Modules/_tkinter.c:46:10: fatal error: tk.h: No such file or directory 46 | #include <tk.h> | ^~~~~~

As, you can see its expecting package under /usr/local/include. And, your download file might be installed to some other location. You have to either copy the required file or create symlink(softlink) to correct directory (for me it was /usr/local/include)

All of the previous answers do not work for docker images, e.g. for ubuntu, php. Here is the solution:

from php:7.3.30-apache-bullseye
RUN apt-get update && apt-get install -qq tcl tcl-dev tk tk-dev
RUN apt-get install -qq expect expect-dev git


TO INSTALL EXPECT YOU NEED TO REPLACE 100500 PACKAGES


SINCE UBUNTU WENT MAD LOL


WORKDIR /usr/include
RUN git clone https://github.com/christophchamp/expect.git expect_builder && 

cp -r expect_builder/* . && 

cp -r tcl/* .


WORKDIR /usr/include/expect_builder


replace with ./configure --build=x86_64-unknown-linux-gnu for x86


RUN ./configure --build=aarch64-unknown-linux-gnu && 

make && 

cp libexpect5.45.1.so /usr/lib/libexpect.so && 

cp expect /usr/lib/expect


RUN pecl install expect
RUN echo "extension=expect" >> "$PHP_INI_DIR/php.ini-production" && 

mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"


WORKDIR /var/www/html
COPY src/ /var/www/html/


export ports


EXPOSE 80


update flag


RUN echo 'user_flag:FLAG{...}' >> /etc/passwd


change user


USER www-data

The problem

debian and ubuntu does not install tcl into the usr/include location, instead, it is installed inside usr/include/tcl. To resolve this issue, you may copy all of the files to the usr/include. But it will solve only the first part of the problem since apt-get install expect does not install any header files. To solve this part of the issue, I found the following repo which is basically fork of old expect source. You can clone it, unpack and configure / make. After that you have to place it into the proper location.

For me I just copied all the files under /usr/include/tcl/ to /usr/include/ and it worked for me, you should able to see tcl.h file in /usr/include/

sudo cp -r /usr/include/tcl/* /usr/include/
