Topic: Missing dependencies for the following libraries

The content of this topic has been archived on 13 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Hello friends,

I am trying to cross compile a package for openwrt. I am using the "OpenWrt-SDK-15.05.1-ramips-mt7688_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64.tar.bz2" SDK.

I faced the missing dependencies problem. This is the error:

Package beacon_server is missing dependencies for the following libraries:
libc.so.6
libpaho-mqtt3c.so.1
libwebsockets.so.9

Actually i also faced the missing dependencies for this library.

libbluetooth.so.3

  But i solved it with adding this line to the makefile.

DEPENDS:=+bluez-libs

  But i cant solve these libraries. So can you help me for this problem?

This is the Makefile for my package

##############################################
# OpenWrt Makefile for helloworld program
#
#
# Most of the variables used here are defined in
# the include directives below. We just need to 
# specify a basic description of the package, 
# where to build our program, where to find 
# the source files, and where to install the 
# compiled program on the router. 
# 
# Be very careful of spacing in this file.
# Indents should be tabs, not spaces, and 
# there should be no trailing whitespace in
# lines that are not commented.
# 
##############################################

include $(TOPDIR)/rules.mk

# Name and release number of this package
PKG_NAME:=beacon_server
PKG_RELEASE:=1


# This specifies the directory where we're going to build the program.  
# The root build directory, $(BUILD_DIR), is by default the build_mipsel 
# directory in your OpenWrt SDK directory
PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME)


include $(INCLUDE_DIR)/package.mk



# Specify package information for this program. 
# The variables defined here should be self explanatory.
# If you are running Kamikaze, delete the DESCRIPTION 
# variable below and uncomment the Kamikaze define
# directive for the description below
define Package/beacon_server
    SECTION:=utils
    CATEGORY:=Utilities
    TITLE:=beacon_server -- prints a snarky message
    DEPENDS:=+bluez-libs +libc +libmosquitto +libmosquitto-nossl 
endef


# Uncomment portion below for Kamikaze and delete DESCRIPTION variable above
define Package/beacon_server/description
    If you can't figure out what this program does, you're probably
    brain-dead and need immediate medical attention.
endef



# Specify what needs to be done to prepare for building the package.
# In our case, we need to copy the source files to the build directory.
# This is NOT the default.  The default uses the PKG_SOURCE_URL and the
# PKG_SOURCE which is not defined here to download the source from the web.
# In order to just build a simple program that we have just written, it is
# much easier to do it this way.
define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(CP) ./src/* $(PKG_BUILD_DIR)/
endef


# We do not need to define Build/Configure or Build/Compile directives
# The defaults are appropriate for compiling a simple program such as this one


# Specify where and how to install the program. Since we only have one file, 
# the helloworld executable, install it by copying it to the /bin directory on
# the router. The $(1) variable represents the root directory on the router running 
# OpenWrt. The $(INSTALL_DIR) variable contains a command to prepare the install 
# directory if it does not already exist.  Likewise $(INSTALL_BIN) contains the 
# command to copy the binary file from its current location (in our case the build
# directory) to the install directory.
define Package/beacon_server/install
    $(INSTALL_DIR) $(1)/bin
    $(INSTALL_BIN) $(PKG_BUILD_DIR)/beacon_server $(1)/bin/
endef


# This line executes the necessary commands to compile our program.
# The above define directives specify all the information needed, but this
# line calls BuildPackage which in turn actually uses this information to
# build a package.
$(eval $(call BuildPackage,beacon_server))

Thank you in advance.

you'll need to do some googling to find the proper syntax for the dependencies, in the meantime, a quick and dirty way to bypass these errors is to compile with the -i (ignore errors) flag. just add it to the end of you compile instruction...

make package/<package name>/compile V=99 -i

keep in mind this will ignore ALL errors so use it wisely ....

The discussion might have continued from here.
