Yeah it worked once that path was resolved. Thanks!
I have successfully compiled source code and build is generated but when running this command to launch lora app server it is not working
sudo ./lora_app_server --postgres-dns “postgres://loraserver_as:dbpassword@localhost/loraserver_as?sslmode=disable” --jwt-secret XXXXXXXXX --http-tls-cert /etc/lora-app-server/certs/http.pem --http-tls-key /etc/lora-app-server/certs/http-key.pem --db-automigrate --http-bind 0.0.0.0:8080
Output
sudo: ./lora_app_server: command not found
Can any one please help me what i am doing wrong

Can any one let me know what can be the issue I am not able to understand
all other service is in running state !
Thank you @Brocaar I read the link you sent. I have tried to follow all the tips you have proposed in this topic, but the error still exists. Can the problem occur during the installation “gccgo” or “buffers compilations” (installation linked to the compiler Go) according to you ???
Result =>
With the migration from dep to go modules (for managing dependencies) and https://github.com/brocaar/lora-app-server/commit/361e2b2412fe5483a73051b4dae5449b5e4d0730 (in master), make api
should now result in the same output for everybody as the tools are now properly versioned in the go.mod
file
Thank you very much Brocaar !!
I redo the installations with the following links: “https://www.loraserver.io/lora-app-server/community/source/” .
I get the following results But I can not know where exactly the problem exists.
You can help me if he wants to please ! !
Hello,
First of all thank you @brocaar for your effort to deliver a really good loraserver project.
I am trying to compile manually lora app server.
First of all, I followed the documentation on loraserver.io and I did the following :
- Install Go
- Install protocolbuf
- install npm and nodejs. Here is the output of the version command for each module :
node --version
v8.10.0
npm --version
6.5.0
Then I cloned lora-app-server github project and did make dev-requirements ui-requirements.
For dev-requirements, everything is fine.
for ui-requirements, I have the following issue :
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: Xmailto:fsevents@1.2.4 (node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“x64”})
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.7 (node_modules/chokidar/node_modules/fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.7: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“x64”})
added 1954 packages from 1679 contributors and audited 36656 packages in 30.82s
found 87 vulnerabilities (63 low, 9 moderate, 15 high)
run npm audit fix
to fix them, or npm audit
for details
After that, if i do make build, the executable will be generated. If I try to launch it, it work but if I try to access the web interface, I can see only vendor and swagger on the web page. The same result of this issue : Compiling the LoRa App Server source-code
I think that this is related to the error that I got when I did make ui-requirements.
Any ideas what could be the problem?
I have to use docker in order to compile lora app server?
Thanks in advance.
Regards,
Please use the provided Docker Compose environment to build binaries as a starting point. It will setup all requirements in a Docker container for you. It is the same environment used for the provided binaries
Hi Sir,
I am also working on LoRa Server I followed your process of cloning files from github.when I execute command SUDO MAKE it gives an error attached below.! pic a Screenshot%20from%202019-08-21%2011-36-48|690x68
@shuangcai_huang and @brocaar
please help me in debugging this
As i am beginner as well as a fresher i need some help in debugging this. I also did make requirements ui-requirements it didn’t worked for me as in pic b
Anyone’s help can make me up confident.
Thankyou.
You ask about LoRa Server, show a screenshot about LoRa Gateway Bridge and post this in the LoRa App Server topic Please use correct topic the next time!
Anyway, please use the provided Docker environment for compiling. It provides you with a pre-setup development environment. See for LoRa App Server https://www.loraserver.io/lora-app-server/community/source/. For the other components you will find the same document, the commands might be slightly different.
Hi @shuangcai_huang
I did your procedure completely. And it is quite successfull.
I want to know two things -
1] I am getting above images which can be accessed by port localhost:5000 when I do this, first image is seen as shared.
Next, when I do localhost:5000/#/login it shows the second image and so on for /network-server etc…
I know I have to merge all the webpages one by one, but i am new guy to handle go language & Postgres
How to merge all the files required ?
2] When I do ./lora-app-server after cd build I am facing some issues in connecting Database (postgres)
WARN[0000] storage: ping PostgreSQL database error, will retry in 2s error="pq: password authentication failed for user “root”"
and I also tried with your above procedure
sudo ./lora_app_server --postgres-dns “postgres://loraserver_as:dbpassword@localhost/loraserver_as?sslmode=disable” --jwt-secret XXXXXXXXX --http-tls-cert /etc/lora-app-server/certs/http.pem --http-tls-key /etc/lora-app-server/certs/http-key.pem --db-automigrate --http-bind 0.0.0.0:8080
It didn’t worked for me.
@brocaar Hi sir,
Thank you for the support till now, I have learnt a lot about LoRa with help of your documents.
Now, I am trying to compile and run the LoRa Server Manually. If you have understood what @shuangcai_huang has done then please do help me in completing this too.
sudo ./lora_app_server --postgres-dns “postgres://loraserver_as:dbpassword@localhost/loraserver_as?sslmode=disable” --jwt-secret XXXXXXXXX --http-tls-cert /etc/lora-app-server/certs/http.pem --http-tls-key /etc/lora-app-server/certs/http-key.pem --db-automigrate --http-bind 0.0.0.0:8080
I am trying to understand this above code
i have understood some of the parts,
jwt-secret is nothing but doing openssl rand -base64 32 and pasting in place of XXXXXXXX
Please help me completing this project.
Thank you,
Sadashiv
Any help for me please…
for this above post which i posted yesterday
Hello, I compiled the Lora server version of Linux arm in win10 64 bits. The commands I executed are as follows: go-bindata has been installed, migrations. go has been compiled, migrations. go has not been prompted for any errors, but the main. go compiled failed, look forward to your reply.
You need to build statics
and migrations
first. Use the Makefile
to build the project, it already takes care of these issues.
Thank you. The problem is that migrations failed to generate
In addition, can the compiled migrations_gen.go be published together with the code?
Your screenshot doesn’t suggest that. Instead, it suggests you’re trying to generate things in the wrong way. So again, use the Makefile
to do the generation (check what internal/statics internal/migrations
does).
I can’t answer that one.
