Error in compiling
hey, I tried to compile the WiFiNatRouter sketch and I get an error:
Build options changed, rebuilding all /bin/sh: -c: line 0: unexpected EOF while looking for matching `"' /bin/sh: -c: line 1: syntax error: unexpected end of file make: *** [build/api/api_lib.o] Error 2 exit status 2 Error compiling for board NodeMCU 1.0 (ESP-12E Module).
help, please
No, when I try in another computer i get: WiFiNatRouter:3:28: error: lwip/lwip_napt.h: No such file or directory #include "lwip/lwip_napt.h" ^ compilation terminated. exit status 1 lwip/lwip_napt.h: No such file or directory
Okay, the second error is "normal", as the lwip_napt.h is not part of the standard liblwip. Please check the following:
- use the second (standard) setup, chose a builtin example, let's say the Basic Webserver, and compile with the "lwip 1.4 from sources" option.
- if this fails, you have some problems with your Arduino installation
- if this works, try to replace the lwip with my extension - should still work
- if yes, you are ready to go on with NAT...
when I try to upload example "HelloServer" with lwip variant "V2 Lower Memory (no features)" its work when I try to upload example "HelloServer" with lwip variant "lwip 1.4 from sources" it doesn't work and I get this error: exec: "make": executable file not found in %PATH% Error compiling for board NodeMCU 1.0 (ESP-12E Module).
Must to say that I didn't find the exact directory of ".../packages/esp8266/hardware/esp8266/2.5.0/tools/sdk/" but my directory is: ...\Documents\Arduino\hardware\esp8266com\esp8266\tools\sdk
Path is okay. Problem is, that you are compiling on Windows and your environment doesn't have the make tool. That's not a specific issue of this lib, but a general issue with the Arduino on Windows. Could you try on Linux? Maybe Google helps...?
hey, I Succeeded to recompile (in Windows) the lib and i get a new "liblwip_src.a" file and I put him in the lib folder. it still not working, the same error. Do I have something more to do?
You will need the includes from my lib. Replace the lwip/include drectory with the one from my repo.
what do you mean i need the includes from your lib? I replace the lwip folder like you write, run the MakeFile and replace the "liblwip_src.a". in addition I run "fix_sdk_libs.sh" like write in the README file (in lib folder)
_## Updating SDK libraries
- Copy .a files from SDK
libdirectory to this directory - Run
fix_sdk_libs.sh_
I did this ugly to step up the direction error code snipped : _#include <ESP8266WiFi.h>
#include "C:/Users/hezi/Documents/Arduino/hardware/esp8266com/esp8266/tools/sdk/lwip/include/lwip/lwip_napt.h"
#include "C:/Users/hezi/Documents/Arduino/hardware/esp8266com/esp8266/tools/sdk/lwip/include/lwip/app/dhcpserver.h"_
and I get: ..... exit status 1 'IP_NAPT_MAX' was not declared in this scope ........
I success to solved this, i think this is a bug because need to add #include <ESP8266WiFi.h> #define IP_NAPT 1 #define IP_FORWARD 1
now I have this problem a lot of time: c:/users/hezi/appdata/local/arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/2.5.0-3-20ed2b9/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld.exe: C:\Users\hezi\AppData\Local\Temp\arduino_build_370994\sketch\WiFiNatRouter.ino.cpp.o:(.text.setup+0x44): undefined reference to `ip_napt_init'
Values are in lwip_napt.h:
/* Default size of the tables used for NAPT */
#define IP_NAPT_MAX 512
#define IP_PORTMAP_MAX 32
You are obviously not linking against the correct lib or you didn't include lwip_napt.h correctly.
You are right but have this: #if IP_FORWARD #if IP_NAPT
/* Default size of the tables used for NAPT / #define IP_NAPT_MAX 512 #define IP_PORTMAP_MAX 32 . . #endif / IP_NAPT / #endif / IP_FORWARD */
that make to not compile the header.
so i dont know what to do i have a lot of problems Do you think that if i do this project on Linux it will be easier? what do you recommend?
hi . i have same error in compiling exec: "make": executable file not found in $PATH Error compiling for board NodeMCU 1.0 (ESP-12E Module). i am in linux environment i placed your lwip folder in /home/emad/.arduino15/packages/esp8266/hardware/esp8266/2.5.0/tools/sdk/ like you said. please help me.i really need this for my project
Guess you tried this on Windows?
no .i am in linux.kubuntu 18.04 i do evrything said in repasetory but still have this error
If you type "make" on the commandline - does ist find the command? If not you probably have to install it.

thats worked. i install make and i can compile and upload it on my nodeMCU .thank you.
hi again .i have quastion. how much is muximum speed of this? i cant get more than 50 KB!!!!!!
Depends on the signal strength ond loss rate - under good conditions about 4-5 MBit are possible.
hi. sorry its me again.i have another quastion. struct pbuf { /** next pbuf in singly linked pbuf chain */ struct pbuf *next;
/** pointer to the actual data in the buffer */ void *payload;
/**
- total length of this buffer and all next buffers in chain
- belonging to the same packet.
- For non-queue packet chains this is the invariant:
- p->tot_len == p->len + (p->next? p->next->tot_len: 0) */ u16_t tot_len;
/** length of this buffer */ u16_t len;
/** pbuf_type as u8_t instead of enum to save space */ u8_t /pbuf_type/ type;
/** misc flags */ u8_t flags;
/**
- the reference count always equals the number of pointers
- that refer to this pbuf. This can be pointers from an application,
- the stack itself, or pbuf->next pointers from a chain. */ u16_t ref;
/* add a pointer for esf_buf */ void * eb; };
its pbuf struct in pbuf.h file .iwant to know what is unit of len and tot_len attributes of this struct?and sum of len can be used to meter trafic that pass from esp?
uint is bytes, len is the size of this buffer and tot_len the payload length of the complete buffer chain (in almost any case you have yu´´just one buffer here). You can add up tot_len to meter the traffic.
Hello, here is the procedure to install and compile the library in Windows (7, 8.1 and 10). (thanks for the file "liblwip_src.a").
1) Downloading files :
Download Arduino IDE 1.8.9 (portable) :
https://downloads.arduino.cc/arduino-1.8.9-windows.zip
Download "lwip_nat_arduino-master.zip" :
https://codeload.github.com/martin-ger/lwip_nat_arduino/zip/master
Download "hh2.golden.exe" (402 bytes) :
https://github.com/pts/pts-tinype/raw/master/hh2.golden.exe
2) Configure Arduino with ESP8266 library :
Unzip "arduino-1.8.9-windows.zip" to "C:\App\arduino-ide\"
Makedir "portable" in "C:\App\arduino-ide\"
Create new file : "C:\App\arduino-ide\portable\preferences.txt"
Add line with :
boardsmanager.additional.urls=http://arduino.esp8266.com/stable/package_esp8266com_index.json
Open IDE Arduino and install ESP8266 library in menu :
Tools / Boards: "Arduino..." / Boards Manager
3) Install the lwip_nat_arduino library :
Copy and rename "hh2.golden.exe" to "C:\App\arduino-ide\make.exe"
(to have an empty "make" utility)
Open "lwip_nat_arduino-master.zip"
Next operation in folder :
"C:\App\arduino-ide\portable\packages\esp8266\hardware\esp8266\2.5.2\tools\"
Rename lwip\ with lwip.orig\ in sdk\
Unzip lwip\ in sdk\lwip\
Unzip liblwip_src.a in sdk\lib\
4) Change the compilation mode :
Menu : Tools / lwIP Variant: "v1.4 Compile from source"
Menu : Tools / Erase Flash: "Sketch + WiFi Settings"
