Package is missing dependencies for libraries - OpenWRT

Question

I am trying to compile OpenWRT with a custom package I have made inside it. Here is the OpenWRT Makefile for my package:

#
# Copyright (C) 2008 OpenWrt.org
#
# This is free software, licensed under the GNU General Public License v2.
# See /LICENSE for more information.
#
# $Id$

include $(TOPDIR)/rules.mk

PKG_NAME:=amld
PKG_RELEASE:=1

include $(INCLUDE_DIR)/package.mk

define Package/amld
 SECTION:=utils
 CATEGORY:=Utilities
 TITLE:=amld -- prints a snarky message  
 DEPENDS:=+libssl +libcrypto +librt
endef

define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(CP) ./src/* $(PKG_BUILD_DIR)/
endef

define Build/Configure
endef

define Build/Compile
    $(MAKE) -C $(PKG_BUILD_DIR) $(TARGET_CONFIGURE_OPTS)
endef

define Package/amld/install
    $(INSTALL_DIR) $(1)/bin
    $(INSTALL_BIN) $(PKG_BUILD_DIR)/amld $(1)/bin/
endef

$(eval $(call BuildPackage,amld))

When I compile I get the following error:

Package amld is missing dependencies for the following libraries:
libcrypto.so.1.0.0
librt.so.0
libssl.so.1.0.0

I am unsure of what to add, does anybody have any ideas? Thanks

Edit

Here is my Makefile for my package:

LDFLAGS=-lssl -lcrypto -lrt
CFLAGS=-g -I /usr/lib/i386-linux-gnu

all: amlpkcs12 amld

amlpkcs12:amlpkcs12.o
    $(CC) amlpkcs12.o -g -o amlpkcs12 $(LDFLAGS)

amld: amld.o iot.o bridge.o sysconf.o
    $(CC) bridge.o iot.o amld.o sysconf.o -g -o amld $(LDFLAGS)

amlpkcs12.o: amlpkcs12.c
    $(CC) $(CFLAGS) -c  amlpkcs12.c

amld.o: amld.c
    $(CC) $(CFLAGS) -c -g -DVERSION=\"1.0\" amld.c

sysconf.o: sysconf.c sysconf.h
    $(CC) $(CFLAGS) -c sysconf.c

bridge.o:bridge.c bridge.h iot.h
    $(CC) $(CFLAGS) -c bridge.c

iot.o: iot.c iot.h
    $(CC) $(CFLAGS) -c -g iot.c

clean:
    rm *.o amlpkcs12 amld

Also see my question and answer here if you're still having trouble.

Answer 1

Finally got it, had to add change

$(eval $(call BuildPackage,amld))

to

$(eval $(call BuildPackage,amld,+libopenssl))

Full Makefile:

include $(TOPDIR)/rules.mk

PKG_NAME:=amld
PKG_RELEASE:=1

TARGET_LDFLAGS+=/usr/include/openssl
PKG_BUILD_DEPENDS:=libopenssl

include $(INCLUDE_DIR)/package.mk

define Package/amld
 SECTION:=utils
 DEPENDS:=+libopenssl
 CATEGORY:=Utilities
 TITLE:=amld -- AccessMyLan Daemon
endef

define Build/Prepare
    mkdir -p $(PKG_BUILD_DIR)
    $(CP) ./files/* $(PKG_BUILD_DIR)/
endef

define Build/Compile
    $(MAKE) -C $(PKG_BUILD_DIR) $(TARGET_CONFIGURE_OPTS)
endef

define Package/amld/install
    $(INSTALL_DIR) $(1)/bin
    $(INSTALL_BIN) $(PKG_BUILD_DIR)/amld $(1)/bin/
endef

$(eval $(call BuildPackage,amld,+libopenssl))

Answer 2

Please check OpenWRT\tmp\.config-package.in . This has the dependency tree generated as soon as build starts. It can give some hints

Answer 3

If you recompiled a package that produces a new lib that's not being installed in build_dir/root-xyz, and that lib is now needed by another package (for example you rebuilt gcc and enabled libasan.so, so now packages that require libasan.so will complain), you can fix things up manually:

• copy the new libs manually into build_dir
• add the new libs to the generated provides file (e.g. libc.provides)
• re-run make for that package
