So I am trying to get lejos (the software for lego robots) to work in my eclipse but when i click the lejos nxj item in the eclipse toolbar and select upload firmware I get the following error
Building firmware image.
VM file: C:\Program Files (x86)\leJOS NXJ\bin\lejos_nxt_rom.bin
Menu file: C:\Program Files (x86)\leJOS NXJ\bin\StartUpText.bin
Magic string found at offset 0x40
VM size: 55712 bytes.
Menu size: 44132 bytes.
Total image size 99940/100352 bytes.
Locating device in firmware update mode.
flashing the firmware failed
lejos.pc.comm.NXTCommException: cannot load library C:\Program Files (x86)\leJOS NXJ\lib\pc\native\jfantom.dll
Caused by lejos.util.jni.JNIException: cannot load library C:\Program Files (x86)\leJOS NXJ\lib\pc\native\jfantom.dll
Caused by java.lang.UnsatisfiedLinkError: C:\Program Files (x86)\leJOS NXJ\lib\pc\native\jfantom.dll: Can't find dependent libraries
See Eclipse error log for detailed stack trace.
anybody has an idea whats going on. I check the directory and the file is there…
This is the content of log file from eclipse
