There are many common compiling issues that users often run into. Here are some of the more common problems, and how to resolve them.
First, let’s take a look at some of the errors you may encounter when running the configure script.
If you receive the following error while attempting to run the configure script, you must install the gcc compiler and its dependencies:
configure: error: no acceptable C compiler found in $PATH
The following packages are required for gcc:
gcc
cpp
glibc-headers
glibc-devel
glibc-kernheaders
These can be installed manually, by copying the files off of
your distribution disks, or through the yum
package manager, with the command yum install
gcc
.
The following error will be displayed if no C++ preprocessor is found installed on the system. You must install the gcc-c++ package and its dependencies:
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
The
following packages are required for the gcc-c++
preprocessor; installed by running yum
install gcc-c++
:
gcc-c++
libstdc++-devel
The following error may be encountered during initialization of the configure script if the libtermcap-devel package is not installed:
configure: error: *** termcap support not found
The following file is required in order to compile Asterisk; it
can be installed with the yum install
libtermcap-devel
command:
libtermcap-devel
You may also run into errors when compiling Zaptel. Here are some of the most commonly occurring problems, and what to do about them. If your error is not listed below, see the previous section as your error may be covered there.
You will receive the following error if you attempt to build Zaptel without the gcc compiler installed:
make: cc: Command not found make: *** [gendigits.o] Error 127
Be sure to install gcc and its dependencies. For more information, see the section called “configure: error: no acceptable C compiler found in $PATH” in the previous section.
The TDM400P cards require the PCI bus to be version 2.2. If you attempt to load the Zapata telephony drivers with an older version, you may get the following errors:
The only way to resolve these errors is to use a newer motherboard that supports PCI version 2.2:
The ztdummy driver requires that a UHCI USB controller be available on Linux 2.4 kernels (the USB controller is not a requirement on Linux 2.6 kernels, because they are capable of generating the 1 kHz timing reference). There exists a secondary kind of controller, known as OHCI, which is not compatible with the ztdummy driver. If the UHCI USB controller is not accessible on Linux 2.4 kernels, the following error will occur:
/lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol unlink_td /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol alloc_td /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol delete_desc /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol uhci_devices /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol uhci_interrupt /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol fill_td /lib/modules/2.4.22/misc/ztdummy.o: /lib/modules/2.4.22/misc/ztdummy.o: unresolved symbol insert_td_horizontal /lib/modules/2.4.22/misc/ztdummy.o: insmod /lib/modules/2.4.22/misc/ztdummy.o failed /lib/modules/2.4.22/misc/ztdummy.o: insmod ztdummy failed
You can verify that you have the correct style of USB controller
and its associated drivers with the lsmod
command:
# lsmod
Module Size Used by
usb_uhci 26412 0
usbcore 79040 1 [hid usb-uhci]
As you can see in the example above, you are looking to make sure that the usbcore and usb_uhci modules are loaded. If these modules are not loaded, be sure that USB has been activated within your BIOS and that the modules exist.
If the USB drivers are not loaded, you can still check which
type of USB controller you have with the dmesg
command:
# dmesg | grep -i usb
To verify that you indeed have a UHCI USB controller, look for the following lines:
uhci_hcd 0000:00:04.2: new USB bus registered, assigned bus number 1 hub 1-0:1.0: USB hub found uhci_hcd 0000:00:04.3: new USB bus registered, assigned bus number 2 hub 2-0:1.0: USB hub found
If you experience depmod
errors during
compilation, you more than likely don’t have a symbolic link to your
Linux kernel sources. If you don’t have your Linux kernel sources
installed, retrieve the sources for your installed kernel, install
them, and create a symbolic link against
/usr/src/linux-2.4. The following is an
example of a depmod
error:
depmod: *** Unresolved symbols in /lib/modules/2.4.22/kernel/drivers/block/ loop.o
