I'm getting the following message when i run protoc -version in my ubuntu terminal.
Unknown flag: -v
Earlier to this, I had got the following error when I ran protoc -version. I found a solution through google and ran "sudo ldconfig /usr/local/lib". After running that, I'm getting the Unknown flag message as mentioned above. Can anyone help me to resolve this? Thanks in advance.
protoc: error while loading shared libraries: libprotoc.so.9: cannot open shared object file: No such file or directory
Long flags require two dashes. Try:
protoc --version
(Common Unix convention says that if you write -abc (with one dash), it means the same thing as -a -b -c, which is why you get the error saying that there is no flag -v. Admittedly, there are a lot of Unix programs that don't follow this rule, but protoc does follow it.)

When running Go code on Mac M2 (important, because installation of related libs work differently on Linux) that imports "github.com/zergon321/reisen" I got this:
# github.com/zergon321/reisen
/Users/ido/go/pkg/mod/github.com/zergon321/reisen#v0.1.4/audio.go:4:11: fatal error: 'libavcodec/avcodec.h' file not found
#include <libavcodec/avcodec.h>
^~~~~~~~~~~~~~~~~~~~~~
1 error generated.
I have ffmpeg (includes the libavcodec/avcodec.h header) installed using brew
brew install ffmpeg
but it doesn't get picked up by itself.
This worked to fix it:
If you indeed installed ffmpeg with brew, the header file should be there -> /opt/homebrew/Cellar/ffmpeg/5.1.2/include/libavcodec/avcodec.h (lib version could be different).
If it is not there for some reason, you can try to locate the header file using find / -name "avcodec.h"
Once you have established avcodec.h's location, note the full path to the /include directory and run your go code passing the following flag:
CGO_CPPFLAGS="-I<path/to/include/directory>" go run <your file name or a period>
The full command for me looked like this:
CGO_CPPFLAGS="-I/opt/homebrew/Cellar/ffmpeg/5.1.2/include" go run .
I am using OMNet++ 6 pre11 with INET 4.3.2 and it is working fine in IDE environment.
But, when I am trying to run INET showcase examples ( wireless/sensornetwork/omnetpp.ini) from the ubuntu terminal, I am getting the following error:
Command
opp_run -m -u Cmdenv -n ../../../src:../..:../../../tutorials:../../../showcases -l ../../../src/INET omnetpp.ini -c BMac
Error
<!> Error: More than one package.ned file for package 'inet.showcases': '/home/fa/Downloads/inet-4.3.2-src/inet4.3/showcases/package.ned' and '/home/fa/Downloads/inet-4.3.2-src/inet4.3/showcases/package.ned'
Would anyone please suggest the solution? Thank you.
This is a known issue in 6.0 preview 11 and 12, caused by the fact that the same directory is added multiple times in the NED path. My guess is that ../.. and ../../../showcases is the same directory. I'm not sure where that ../.. is coming from, but try to get rid of it.
As a side note, this issue was fixed in 6.0pre13 version.
This is not a duplicate question

When I execute the following command

An error occurred:

Where is the problem, please master guidance.
This issue is related with your PATH variable, please set it again.
I can see a typo of an extra trailing apostrophe(') in this line of PATH variable. /Users/chezixin/go:/Users/chezixin/go/bin':
Try updating it to
/Users/chezixin/go:/Users/chezixin/go/bin:
For anyone facing a similar issue, but it was not the case of an invalid PATH variable, I very much sympathize with you.
I realized that I had to install the compiler (again?) before it started working. I hadn't installed it before, but it appeared to already be downloaded. I guess I had to install it again or update it.
I personally was using betterproto, and I followed the instructions here to install it with the protoc plugin and try out their example.
I have deployed PhotonOS using directions from photon and VIC configuration, while running command docker run -v $(pwd):/go/src/github.com/vmware/vic \-w /go/src/github.com/vmware/vic golang:1.6 make all
an Error appears:
Please install go1.7 (found: go version go1.6.3 linux/amd64)
Makefile:152: recipe for target 'goversion' failed
make: *** [goversion] Error 1
`
to solve it I have tried to update
go1.6.3 to go1.7 using solution - changeing go version manually
after steps go version is showing go1.4.2, but the previous error still complains on go version 1.6.3.
Also, I have tried to install "gvm" using bash < <(curl -s -S -L https://raw.github.com/moovweb/gvm/master/binscripts/gvm-installer) , whenever I try to call gvm install go1.7 it brings
-bash: gvm: command not found
whenever I retry running gvm-installer it says
ERROR: Already installed!
Any help is highly appreciated!!
use :
docker run -v $(pwd):/go/src/github.com/vmware/vic \-w /go/src/github.com/vmware/vic golang:1.7 make all
command instead, that will work on PhotonOS
I just managed to get "dot" installed correctly, per a warning in phpDocumentor. Now when I try to build my docs, however, I am getting the exception:

An error occurred while creating the graph; GraphViz returned: Format: "svg" not recognized. Use one of:
Does anyone know how to get past this? The command I am running is:
php phpdoc.php -c mypath/phpdoc.dist.xml -p
I had this same issue, running sudo dot -c fixed it for me.
